TiO2-PANi composites were synthesized by cyclic voltammetry method in potential area of -0,4 - 1,1 V versus Ag/AgCV saturated KCl electrode at scan rate of 20 mV/s in solution of 0.1 M H2SO4 + 0.1 M 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 nanostructured TiO2-PANi composite prepared under cycle number of 150 was successfully obtaining with stable electrochemical activity and no pitting corrosion on it appeared.
