Polyaniline (PANI)/TiO2 nanocomposite samples with various dopant percentages of TiO2 were synthesized at room temperature using a chemical oxidative polymerization method. The doping effect of TiO2 was characterized and evaluated by X-ray diffraction (XRD) and scanning electron microscopy (SEM) technique. X-ray pattern confirms the formation polyaniline and as the TiO2 percentage was increased, the amorphous nature disappeared and the composites became more strongly oriented and SEM study shows that TiO2 nanoparticles have a strong effect on the morphology of composites with average grain size of 10-20nm nm. The electrical conductivity measurements indicate that the conductivity of composites at low TiO2 content is much higher than that of the PANI, while with the increasing contents of TiO2, the conductivity shows an orderly decrease. DC conductivity increasing as content of TiO2 and temperature in increased.
