Study on synthesis of TiO2-PANi composite on titanium subtrate by cyclic voltametry

Abstract

TiO2-PANi composites were synthesized by cyclic voltammetry method in potential area of-0,4-ỉ I,IV versus Ag/AgCl/ saturated KCI electrode at scan rale of 20 mV/s in solution of O.IM H2SO4 + O.IM aniline + TiO2 sol gel (TiO2 . aniline 1:12) with cycle number varried from 50 to 200 using an electrochemical workstation IM6 (Germany). The properties of materials were analysed by IR-spectrum, SEM and TEM-images. Their electrochemical properties were observed by cyclic voltammetry and cyclic polarization graphs in 0.5 M H2SO4. The results showed that nanoslructured TiO2-PANi composite prepared under cycle number of 150 was successfully obtaining with stable electrochemical activity and no pitting corrosion on it appeared.
