摘要：

The analysis of the electrochemical and spectroscopic properties of a composite material obtained starting from the polyaniline and TiO2 in H2SO4 medium, using cyclic voltamperometry, shows three redox couples characteristic of the different oxidation and reduction states of produced polymer. The electroactivity of the composite in acid medium was better than that obtained in basic medium. The impedance spectroscopy study shows that the resistance of the film increases with the aniline concentration, but is not significantly affected by the amount of TiO2 incorporated in polymer. The increase of pH decreases the resistance of the films and consequently increases its conductivity. (C) 2011 Elsevier B.V. All rights reserved.
