Studies on polyaniline and colloidal TiO2 composites

Abstract This study deals with the various aspects of incorporation of colloidal TiO 2 in polyaniline during the electrochemical polymerization of aniline, aiming to study the effect of photoconducting inorganic semiconductor on the thermal stability and potential application of a new composite, as revealed by powder X-ray diffraction (XRD), particle size analysis, electronic spectra and thermal analysis. The particle size of TiO 2 has increased during incorporation in polyaniline matrix due to the formation of the composite. It is possible to achieve 80.6% of TiO 2 incoporation in the polyaniline matrix by using colloidal TiO 2 .
