In this study, the surface of silica nanoparticles was modified by three Silanol groups: VTMES (vinyl tries; 2-metoxy; ethoxy Silane), GAPTMS( δ-amino propyl trim ethyl Silone), and PTMS( propyl trim ethyl Silone). The purpose of this study is that the surface of the silica nanoparticle hydrophilic with organosilanol compounds derived from silica has been modified to be adapted with hydrophobic polyolefin and improved the properties of new nano-composite materials. Silica nanoparticles were modified at three levels 1, 3, and 5% by weight. To study the morphology of silica nanoparticles modified the techniques of electron microscopy (TEM) , (SEM) and thermal analysis (TGA), infrared spectroscopy (FT-IR) was used. The results showed that the subjects with higher surfaces of hydrophobic had been modified further and further reduced water absorption capacity. Silica nanoparticles enhanced the original structure, binding to polymers such as polyolefin and polypropylene is ready to prepare the nanocomposites.
