Polyaniline-manganesetitanatenanocomposites (NCs) with two contents loading of MnTiO₃ were successfully synthesizedvia sol–gel process usingManganese acetyl acetonate, tetra-n-butyltitanate, stearic acid, potassium iodate and sulfuric acid. The prepared PANI/MnTiO3NCs were characterized by energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), UV-vis diffused reflectance spectra (DRS), Particle Size Distribution (PSD)and Zeta Potential. The results indicated that MnTiO₃NPs with particle size between 22 and 30nm were distributed in PANI matrix. The value of direct band gap for MnTiO₃ and the PANI/MnTiO₃NCs with 10 and 20wt% of MnTiO₃NPs loading using the Tauc model came out to be 1.15 Ev, 1.35 and 1.25. Band gap analysis indicates semiconducting behavior of the NCs.
