Effect of TiO2 Nanoparticles on the Properties of PANI

Abstract

Abstract: Polyaniline/TiO₂ nanocomposites was prepared in the presence of titanium dioxide. The incorporation of polymers in the composites was proved by FTIRstudies. The nanocomposites have been characterized by four point probe conductivity measurements, UV-Vis, transmission electron micrograph. The results show that polyaniline/TiO₂ has a higher conductivity(×10^-2) compared with that of EB, the UV-Vis spectra properties of polyaniline/TiO₂ depend on the ratio of TiO₂ to polyaniline. The UV-Vis spectrum of the nanocomposites doped with HCSAshows a red shift and possesses a higher conductivity and better solubility compared with those of nanocomposites and PANI. TEMmicrographies show that TiO₂ nanoparticles are partly coated with the polymer.

Key words: Polyaniline(PANI), Titanium dioxide, Nanocomposites material
