Enhanced Conductive and Optical Properties of TiO₂/PANI Composites Synthesized by in-situ Chemical Oxidation Polymerization Route

Polyaniline titania composites have been investigated due to their unique chemical and physical properties. This study synthesized several PANI/TiO 2 composites with different mol% of PANI using in-situ oxidative polymerization methods. TiO 2 was obtained by coprecipitation methods. The functional group analysis carried out using Fourier transform Infrared reflectance, it was found that PAni/TiO 2 had been successfully created, which was indicated by the absence of new peaks. Based on the results of measuring absorbance in the Ultraviolet-Visible wavelength, it was found that the composite material made had a wider absorption range compared to its constituents. The electrical conductivity of composites was shown to have a higher value than TiO 2. From these results, it was found that the PANI/TiO 2 composite material has greater photoactivity than TiO 2 .
