摘要：

The electro-oxidation behavior of aniline on a Pt surface in acetonitrile+tetrabutylammonium perchlorate (TBAP) solution was investigated using cyclic voltammetry. The effects of aniline concentration and the added acid were elucidated. The polyaniline films were characterized by their cyclic voltammograms in blank solution and dry conductivities were measured using the four-probe technique. As expected from the mechanism of the electro-oxidation of aniline, improvements in the quality and quantity of the polyaniline films were obtained by adding anhydrous acid to the medium. Furthermore, it was found that the concurrent generation of acid through in-situ oxidation of dissolved molecular hydrogen was the most efficient way of improving the polymer yield and properties.
