Polymer Chemistry Innovations: From Smart Polymers to Biomedical and Environmental Applications

Introduction

Polymer chemistry has undergone remarkable transformation since the early development of synthetic plastics in the mid-twentieth century. Initially, polymer research was primarily focused on producing inexpensive and durable materials that could replace natural resources in applications such as packaging, construction, and consumer products¹. Conventional polymers including polyethylene, polypropylene, polystyrene, and poly(vinyl chloride) became widely used due to their ease of manufacture, mechanical strength, and chemical resistance². However, traditional polymer materials were largely designed for structural or bulk applications, with limited emphasis on molecular-level control or functional responsiveness³. Increasing technological demands and environmental concerns gradually highlighted the limitations of conventional plastics, including poor degradability, limited functionality, and long-term environmental persistence⁴.

Advances in polymer synthesis techniques have significantly expanded the capabilities of polymeric materials. Modern polymer chemistry enables precise control over molecular weight, architecture, and functionality through techniques such as controlled and living radical polymerization, ring-opening polymerization, and click chemistry⁵˒⁶. These developments have enabled the design of functional polymers with tailored physicochemical properties and predictable behavior in complex environments. As a result, polymers are no longer regarded merely as passive materials but as dynamic systems capable of responding to external stimuli and performing specific functions⁷˒⁸.

Among these developments, smart or stimuli-responsive polymers have emerged as an important class of advanced materials. These polymers can undergo reversible changes in their physical or chemical properties in response to environmental triggers such as pH, temperature, light, redox conditions, magnetic fields, or enzymatic activity⁹. The ability to engineer polymer responsiveness through molecular architecture and chemical functionalization has opened new possibilities for designing adaptive and multifunctional materials¹⁰˒¹¹.

Smart polymers have attracted considerable attention in biomedical applications, particularly in drug delivery, tissue engineering, and regenerative medicine. Polymeric nanoparticles, hydrogels, micelles, and polymer–drug conjugates can improve drug solubility, enhance therapeutic targeting, and enable controlled or stimuli-triggered drug release¹²˒¹³. Similarly, polymer-based scaffolds and hydrogels with tunable mechanical and biological properties have been widely explored for tissue regeneration and biomedical implants¹⁴˒¹⁵.

At the same time, polymer chemistry plays a crucial role in addressing environmental challenges associated with conventional plastics and industrial pollution. The development of biodegradable and bio-based polymers derived from renewable resources has emerged as an important strategy to reduce environmental impact²⁰˒²¹. In addition, functional polymeric materials are increasingly used in water purification, pollutant adsorption, separation technologies, and recyclable material systems, contributing to sustainable environmental management²²˒²³.

Although biomedical and environmental polymer research have traditionally evolved as separate disciplines, both fields rely on similar structure–property relationships governed by polymer architecture, functionalization, and molecular interactions²⁴˒²⁵. Understanding these shared principles provides opportunities for cross-disciplinary innovation and the development of materials that simultaneously address healthcare and sustainability challenges²⁶˒²⁸.

The objective of this review is to provide a comprehensive overview of recent advances in polymer chemistry, with particular emphasis on smart and functional polymers and their applications in biomedical and environmental systems. The review highlights the fundamental principles governing polymer structure and responsiveness, discusses key applications in healthcare and environmental technologies, and examines safety, regulatory, and sustainability considerations²⁹˒³⁰. Emerging research directions, including artificial intelligence-assisted polymer design, green polymer chemistry, and sustainable materials development, are also discussed to provide insights into future developments in the field³¹–³⁵.

Fundamentals of Polymer Chemistry.

Polymer chemistry provides the molecular framework for designing materials with tunable mechanical, chemical, and functional properties. Understanding polymerization mechanisms, molecular weight characteristics, and structure–property relationships is essential for the rational design of functional and stimuli-responsive polymer systems used in biomedical and environmental applications¹.

Polymerization Techniques

Polymerization processes determine the molecular architecture, composition, and performance of polymeric materials. In step-growth polymerization, multifunctional monomers react progressively to form polymers such as polyesters and polyamides, generally producing materials with broad molecular weight distributions. In contrast, chain-growth polymerization involves the propagation of active centers (radical, cationic, or anionic), enabling rapid formation of high-molecular-weight polymers from vinyl monomers².

Recent advances in controlled or living polymerization techniques, including atom transfer radical polymerization (ATRP), reversible addition–fragmentation chain transfer (RAFT) polymerization, and nitroxide-mediated polymerization (NMP), have significantly improved the precision of polymer synthesis. These techniques enable accurate control over molecular weight, polydispersity, and polymer architecture, facilitating the fabrication of complex structures such as block, graft, and star copolymers. Such control is particularly important for designing smart polymer systems with predictable responsiveness and functionality³as shown in Table 1. These techniques permit the strict regulation of molecular weight, specific polydispersity and more complicated designs like block and graft copolymer, which is essential to smart polymer design⁴.

Table 1: Polymerization Techniques Comparison

Molecular Weight, Polydispersity, and Chain Architecture

Molecular weight and its distribution are critical determinants of polymer properties, influencing viscosity, mechanical strength, solubility, and degradation behavior⁴². The polydispersity index (PDI) reflects the uniformity of polymer chain lengths, where lower values indicate narrower molecular weight distributions and more predictable material performance⁵.

Polymer chain architecture also plays a crucial role in determining material behaviour. Linear, branched, star-shaped, and network polymers exhibit distinct chain dynamics, diffusion characteristics, and mechanical properties. In functional polymer systems, controlled architecture can influence drug loading capacity, diffusion pathways, and interactions with biological or environmental targets. Consequently, precise control over molecular architecture is a fundamental strategy in the development of advanced polymer-based technologies⁶.

Chemical Functionalization and Crosslinking Strategies

Chemical functionalization introduces specific reactive groups into polymer chains, enabling selective interactions with drugs, cells, biomolecules, or environmental pollutants. Functionalization strategies such as copolymerization, post-polymerization modification, and click chemistry provide versatile approaches for tailoring polymer functionality with high specificity⁷.

Crosslinking, achieved through covalent bonds or physical interactions, generates three-dimensional polymer networks such as hydrogels that exhibit enhanced mechanical stability and controlled swelling behaviour. The crosslinking density plays a critical role in determining permeability, responsiveness, and degradation rates in functional polymer systems. These characteristics are particularly important for applications requiring controlled release, adaptive behaviour, or environmental responsiveness⁸.

Structure–Property Relationships

The relationship between polymer structure and physicochemical properties forms the foundation of modern polymer design. Factors such as backbone rigidity, side-chain functionality, crystallinity, and crosslinking density strongly influence thermal stability, mechanical strength, solubility, and stimuli-responsive behavior⁹. Understanding these relationships enables the rational design of polymers with tailored performance for specific biomedical and environmental applications¹⁰.

Advances in polymer chemistry have therefore shifted the focus from simple material synthesis to structure-guided material design, where molecular architecture is engineered to achieve desired functionality and performance. This structure property perspective underpins the development of smart polymers capable of responding to environmental signals and performing complex tasks in advanced technological applications.

Smart and Stimuli-Responsive Polymers

Smart or stimuli-responsive polymers are a recent highly functional material that can reversibly and predictably change their physicochemical characteristics when reacting to external or internal stimuli¹¹. These materials, in contrast to traditional polymers, are engineered to respond to changes in the environment, and convert it to macro-scale responses, including sol-gel transition, swelling-deswelling, shape change, or self-repair¹². This adaptive behaviour has made smart polymers important materials in novel biomedical technology and sustainable material systems¹³.

Stimuli Types: pH, Temperature, Redox, Light, Enzymes, and Magnetic Field

Stimuli-responsive polymers are sometimes generalized according to the type of stimulus used such as an ionizable functional group that can be protonated or deprotonated and the resulting solubility or swelling behavior depends on the stimulus¹⁴. In thermo-responsive polymers, including poly(N-isopropylacrylamide), the critical solution temperature is either lower or higher and sharp phase transitions are possible at physiological temperatures¹⁵.

Redox-responsive polymers are based on reversible oxidation-reduction reactions usually catalyzed by disulfide or ferrocene functionalities and are suitable in intracellular delivery of drugs due to the presence of redox gradient¹⁶. Enzyme-responsive polymers take advantage of biological specificity, whereby the polymers react selectively to enzymatic cleavage, whereas the magnetic-field-responsive systems combine magnetic nanoparticles to produce an externally directed actuation or heating action¹⁷as shown Table 2 and as shown in Figure 2.

Table 2: Smart Polymer Types & Applications

Figure 2: Stimuli-Responsive Polymer Mechanisms Click here to View Figure

Molecular Mechanisms Behind Responsiveness

The smart polymers are responsive due to the change of molecular-level changes in chain conformation, intermolecular interaction or network structure¹⁸. Non-covalent interactions i.e. hydrogen bonding, electrostatic forces, and hydrophobic interactions are changed by external stimuli leading to reversible macroscopic transitions¹⁹. Covalently responsive systems are systems in which cleavage or formation of given bonds causes regulated degradation or restructuring of polymer networks²⁰.

The equilibrium of the enthalptic and the entropic terms determines the acuity and reversibility of response. High response-time, high sensitivity, and low hysteresis require, therefore, precision in molecular design²¹.

Design Strategies for Tunable Response and Reversibility

The synthesis of smart polymers with tunable and reversible responses needs to be very meticulous regarding polymer composition, molecular weight, architecture, and functional group density²². The most common combinations of two or more responsive elements in a single material are block copolymer, graft polymer and interpenetrating networks²³. In controlled/living polymerization methods uniform placement of the responsive segments can be accomplished making behavior predictable²⁴.

Dynamic covalent bonding and supramolecular interaction with covalent bonds helps to increase reversibility, allowing repeats of response cycles without fatigue of the material²⁵. These strategies are very essential in applications that demand long term performance e.g., reusable sensors and adaptive membranes²⁶.

Recent Advances in Self-Healing and Shape-Memory Polymers

A recent major development in smart material design is self-healing polymers, which can autonomously repair mechanical damage by using reversible bonding with hydrogen bonding, metal-ligand coordination or dynamic covalent chemistry²⁷. These materials enhance durability, service life, especially in coating, biomedical implants, and structural²⁸.

Shape-memory polymers are capable of freezing a temporary shape and restoring the original shape when subjected to an external stimulus, which generally is heat or light²⁹. Recent trends have been on multi-shape memory performance, accelerated recovery rates, and bio-compatible systems, which increase their possibilities in minimally invasive medical equipment and soft robotics³⁰. Self-healing and shape-memory polymers are examples of how more complex stimuli-responsive polymer systems are becoming³¹.

Polymer Innovations in Biomedical Applications

Drug Delivery Systems: Polymeric Nanoparticles, Micelles, and Hydrogels

Polymer chemistry has facilitated great breakthroughs in the field of biomedical science by offering materials with adjustable framework, functionality, and disintegration properties³². The control of polymer synthesis and the design of smart materials have broadened the functions of polymers as passive carriers to the responsive systems of dynamic interactions with the biological systems³³. Such developments have especially influenced drug delivery, tissue engineering and implantable medical devices, as well as posing critical issues concerning clinical translation and regulation³⁴ as shown in Figure 3.

Tissue Engineering and Regenerative Medicine

Polymeric scaffolds in tissue engineering are used as temporary matrices that facilitate the adhesion, proliferation and differentiation of cells³⁵. Polymer innovations have allowed the manufacture of scaffolds of known porosity, mechanical strength, and degradation, which closely resembles natural extracellular matrices³⁶. Bone, cartilage, skin, and vascular tissue regeneration Natural polymers, synthetic biodegradable polymers and hybrid systems are all actively investigated in the field of bone and cartilage regeneration³⁷. Biological responsive smart polymers also improve scaffold in terms of remodelling, since these polymers can respond to cellular activity through dynamic remodeling³⁸.

Bioadhesive and Implantable Polymer Systems

Bioadhesive polymers have been recognized to be used in wound closure, mucosal delivery of drugs and surgical sealants³⁹. This may be done by chemical modification of the polymers with functional groups that react with the biological tissues to enhance the adhesion strength and residence time⁴⁰. Fine-tuning of mechanical performance and degradation behavior of implantable polymer systems based on applied polymer chemistry advantages include stents, sutures, orthopedic devices, among others⁴¹. The concepts of shape-memory and self-healing polymers are being tested as well to enhance the performance and life of the implants⁴².

Biodegradability, Biocompatibility, and Controlled Degradation

The biomedical design of polymers has biodegradability and biocompatibility as a key consideration. Mathematically controlled degradation will make polymeric systems execute their designated role and then biodegrade to generate non-toxic byproducts in a manner that is safe. Modulation of degradation kinetics using Polymer chemistry backbone composition, crystallinity and MW. The reproducibility of degradation profiles is, however, a major challenge that has not yet been attained, especially in long-term implants⁴³.

In translational terms, the safety, reproducibility, and manufacturing consistency of polymer based medical products are to be evaluated thoroughly in order to obtain regulatory approval of the products. The scaling up of synthesis, regulation requirements and clinical utility are significant challenges and it is imperative that polymer chemistry and biomedical research be closely integrated with regulatory science⁴³.

Polymer Chemistry in Environmental Applications

Polymer chemistry is currently a key to not only tackling the global environmental issues but also facilitating the creation of materials that aid in the control of pollution, efficiency of resources, and management of materials in a sustainable manner. Progress in functional and smart polymers has seen them being utilized in high-performance wastewater, separation, and circular economy systems, beyond the traditional plastics. The above developments indicate the flexibility of polymer chemistry as one of the most important factors to achieve environmental sustainability⁴⁴.

Water Purification and Pollutant Adsorption

Polymer-based materials are highly used in its purification of water because the materials are tunable in surface chemistry, high adsorption capacity, and processable. Ion-exchange group, chelating ligand bearing functional polymers and hydrophobic functional group functional polymers are effective in extracting heavy metals, dyes, pharmaceuticals and emerging contaminants in water. Hydrogels and nanocomposites made of polymer can also be used to promote adsorption through large surface area and high diffusion rates. Regenerable smart polymer adsorbents which are responsive to pH, ionic strength allow energy-efficient regenerable water treatment systems to minimize secondary waste generation⁴⁵.

Biodegradable and Bio-Based Plastics

The sustainability of the traditional plastics in terms of the environment has necessitated vigorous studies related to biodegradable and bio-based polymer substitutes. Renewable-based polymers, e.g. polylactic acid, polyhydroxyalkanoates and starch-based polymers, have lower carbon footprint and better end-of-life solutions. Polymer chemistry puts in place customization of mechanical properties, processability and degradation rates to suit applications requirements without affecting environmental friendliness. Irrespective of these developments, issues of cost, massive output and regulated deterioration in different environmental circumstances are also quite important⁴⁶.

Polymer Membranes for Separation Technologies

Modern separation technologies based on the use of polymer membranes are in the applications of water desalination, wastewater treatment, and gas separation. Developments in polymer chemistry have seen increased permeability, selectivity and fouling resistance in membranes in terms of controlled molecular architecture and surface modification. The addition of functional fillers and strategies of polymer blending also enhance better performance and longevity of membranes. Adaptive separation behaviour is provided by smart membranes that are able to respond to environmental stimuli, which helps to facilitate more efficient and sustainable processing⁴⁷.

Recycling, Upcycling, and Circular Polymer Economy

The purpose of a circular polymer economy is to reduce waste and maximize the number of reused materials by means of recycling and upcycling. Selective depolymerization and refunctionalization make chemical recycling possible to recover monomers and value-added chemicals in polymer waste. The upcycling strategies are used to convert waste polymers into high-value products by catalytic and polymer-chemical routes. The development of recyclable, biodegradable polymers is widely cited as a fundamental challenge faced by polymer chemists, as it brings the long-term sustainability of materials into line with the focus on the material innovation⁴⁸.

Cross-Domain Structure–Property–Application Relationships

Polymer chemistry offers a common language which connects the molecular structure to the macroscopic performance of biomedical and environmental applications⁴⁹. The differences between these areas in terms of end-use needs and regulatory demands notwithstanding, they are based on similar structure-property relationships that are controlled by polymer architecture, functionalization, and physicochemical behaviour⁵⁰. A systemic evaluation points to the similarity between fundamental principles of polymers as applied in different applications and demonstrates limitations and sustainability trade-offs in domains⁵¹as shown in Table 3.

Table 3: Table: Comparison of Polymer Applications in Biomedical and Environmental Systems

Translation of Polymer Chemistry Principles Across Biomedical and Environmental Uses

At the molecular level, polymer backbone structure, chain flexibility and distribution of functional groups determine both their interactions with biological tissues and other environmental pollutants⁵². Hydrophilic-hydrophobic balance, as an example, regulates the drug encapsulation and release in biomedical systems and also determines the adsorption and transport in water treatment membranes⁵³. On the same note, crosslinked polymer networks that have been developed to have controlled swelling in hydrogels are also used in the parallel mode in pollutant adsorption and controlled permeation technologies⁵⁴.

Stimuli-responsive behaviour demonstrates also the cross-domain translation: pH- and redox-responsive polymers that were initially used in targeted drug delivery have been used to capture selective pollutants and regenerable adsorption systems. These examples highlight the generality of polymer chemistry concepts in apparently unrelated fields of application⁵⁵.

Common Design Rules and Domain-Specific Constraints

There are a number of design rules, which are common in polymer performance in biomedical and environmental aspects⁵⁶. They are accurate control of molecular weight and polydispersity, targeted functionalization to get specificity and regulation of transport and degradation behavior by architecture⁵⁷. Nonetheless, domain specific constraints affect the implementation of these rules to a great extent⁵⁸.

Biomedical polymers should be highly efficient in terms of biocompatibility, sterility and regulatory acceptance, which frequently constrain the usefulness of available chemistries and additives⁵⁹. Contrastingly, environmental polymers focus on strength, low cost, and stability in fluctuate conditions at the cost of quick degradability⁶⁰. To strike a balance between these constraints, there must be a special consideration of polymer design strategies in relation to the intended use⁶¹.

Trade-Offs Between Functionality, Stability, and Sustainability

One such problem in the design of cross-domain polymers entails the trade-offs between high functionality and material stability, and environmental sustainability. Hyperfunctionalized polymers can provide enhanced performance and can be complex to synthesize, expensive and recycle. On the other hand, biodegradable polymers enhance the sustainability, but they might not possess the same mechanical strength or durability in stressful operations⁶².

Polymer scientists are progressively responding to these trade-offs using modular design, hybrid materials, and life-cycle-conscious synthesis methods. This requires the recyclability, controlled degradation, as well as optimization of performance to be integrated into one design structure that will result in next-generation polymers that are both biomedical and environmental-sustainable⁶³.

Safety, Toxicity, and Regulatory Considerations

The increasing background of using polymers in biomedical and environmental use requires strict analysis of safety, toxicity, and the adherence to regulations. Although sophisticated polymer systems are important to consider in terms of functional benefits, chemical structure, degradation, and life-cycle destiny pose substantial issues that need to be resolved through the accountable design and regulation of polymers⁶⁴.

Polymer Toxicity and Degradation Byproducts

Molecular weight, chemical composition, additives, and degradation pathways are some of the factors that determine polymer toxicity. Being said, as harmless as in their bulk form, any degradation of the polymers might produce low-molecular-weight byproducts that can cause cytotoxicity, inflammation, or endocrine disruption. Local pH alteration and tissue irritation due to acidic degradation products of aliphatic polyesters, e.g., can be observed in biomedical systems unless it is controlled appropriately. Polymer chemistry is also important in reducing these impacts as it allows predictable degradation that is non-toxic due to rational backbone and side-chain design⁶⁴.

Long-Term Environmental and Biological Accumulation

Long chain polymers and microplastic fragments are becoming increasingly worrying on long term accumulation in both the environment and living systems. Polymer residues may also settle in the soil and water systems in the environment and cause effects on the organisms, either by physical obstruction, by leaching chemicals or by bio-accumulation. Biomedical Uses Long-term implantation of non-degradable or slowly degradable polymers can result in persistent inflammatory reaction or fibrotic encapsulation. The fate, transport and transformation of polymers are important to understand in order to undertake risk assessment and deployment of materials sustainably⁶⁵.

Regulatory Frameworks for Biomedical and Environmental Polymers

The regulatory when it comes to polymer-based materials is a great difference between biomedical and environmental ones. Medical polymers on which biomedical drug delivery systems, implants, and medical devices are made are under intensive regulatory scrutiny with regard to safety, efficacy, and manufacturing consistency. By comparison, environmental polymers tend to be covered by more general chemical or materials rules, in which the nano- or micro-scaling effects can be inadequately considered. The absence of harmonized international standards is a source of challenges in the area of innovation and commercialization, and there is a need to have science-based and application-specific regulation systems⁶⁶.

Strategies for Safe-by-Design Polymer Chemistry

Safe-by-design polymer chemistry focuses on incorporation of active safety and sustainability concerns in material design. Such approaches are non-toxic monomers and catalysts, controlled degradation pathways, recyclability, and life-cycle assessment at the early development stages. The use of safety testing, environmental impact testing, and regulatory congruency as well as performance optimization will make it possible to create effective and responsible polymers. These practices are also becoming important in terms of securing confidence to the people and the sustainability of polymer-based technologies⁶⁷.

Emerging Trends and Future Perspectives

Digital tools and the need to be sustainable coupled with the growing demand of application-specific performance are bringing polymer chemistry into a new phase. It is anticipated that future trends will focus on predictive design, renewable feedstocks, and intelligent polymer systems that could be used to handle challenges in healthcare and environmental resiliency in an integrated form⁶⁸.

AI-Assisted Polymer Design and Predictive Modelling

The use of artificial intelligence (AI) and machine learning is quickly changing the nature of polymer research, providing the opportunity to predict, using data, the structure-property-performance relationship⁶⁹. The AI-assisted models have the potential to enable discovery of polymers much faster through optimization of monomer selection, polymerization factors and molecular architecture with the benefit of lowered experimental loads⁷⁰. Predictive modelling is especially useful in the design of smart polymers that would have desired responsiveness, degradation behavior, and mechanical properties, thus enhancing the reproducibility and scalability¹⁸. Combining AI with experimentation on high throughput is predicted to transform the process of creating polymers⁷¹.

Green Polymer Chemistry and Renewable Monomers

Green polymer chemistry aims at minimizing the environmental impact by using renewable monomers, benign synthesis pathways and energy efficient processing. More recently, biomass, carbon dioxide, and waste streams are being considered as providing biomass-derived bio-based monomers that are alternative feedstocks to petrochemicals. Innovations in catalytic polymerization and solvent-free or solvent-free methods enhance the responsibility of the environmental production of polymers more. It is the focus of future research to focus on polymers that can integrate high performance, as well as recyclability and controlled biodegradation, as this helps in the upholding of the principles of the circular economy⁶⁴.

Personalized and Precision Polymer Systems in Medicine

Personalized medicine is mandating the need of using individualized polymer systems according to the need of the patient, the disease condition, or genetic makeup. Molecular design Precision polymer platforms can control the release of drugs, deliver them to target locations and facilitate adaptive therapeutic response. Combining the polymer chemistry and diagnostics, biosensors, and AI-based analysis of patient data will help to develop personalized treatment plans. Nevertheless, issues of regulatory approval, consistency of manufacture, and cost will have to be tackled so that mass clinical translation can be facilitated⁷².

Smart Polymers for Climate and Environmental Resilience

There is growing interest in using smart polymers to create climate-adaptive and environmentally resilient uses such as responsive membranes to water scarcity, self-healing infrastructure, and adaptive coatings to energy efficiency⁷³. Recyclable and stimuli-responsive polymers can increase the stability of the system and decrease the use of resources⁷⁴. It will be an important issue in sustainable development in the changing climate to design polymers that could react to environmental stresses like changes in temperature, pollution load, and mechanical destruction⁷⁵.

Conclusion

The polymer chemistry has progressed through the evolution of the traditional plastics to the highly advanced sophisticated science that allows the designing of functional, smart and sustainable materials to be used in advanced applications. The review advances significant breakthroughs in polymerization methods, molecular structure regulation and stimuli-responsible function that have all discussed polymers into dynamic systems that are able to respond to complex biomedical and environmental problems. The polymer-based drug delivery, tissue engineering, and implantable systems show how specific molecular design can enhance the therapeutic efficacy, safety, and clinical performance, and the work in the environmental field indicates the importance of polymers in terms of water purification, separation technologies, recycling, and the idea of the circular economy. One of the major results of this review is the identification of a powerful interdisciplinary synergy since similar structure-property-Application relationships can be used to govern polymer performance in healthcare and environmental-related scenarios despite the different regulatory and operating restrictions. By combining the knowledge of polymer chemistry, materials science, biology, and environmental engineering, transferable design principles can be integrated to achieve faster innovation and achieve sustainability. In the future, new developments such as AI-based polymer design, the use of green and renewable monomers, tailored polymer systems in medicine, and intelligent materials as a climate defence will continue to increase the role of polymer chemistry. Further focus of safe-by-design solutions, life-cycle analysis, and translational preparedness will be necessary in order to help close the divide between laboratory innovations and practical solutions. In general, polymer chemistry is set to become a core of developing future technologies which would be highly performance-based and environmentally friendly and beneficial to the society.
