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
