摘要：

Polyaniline films have been formed at tin dioxide electrodes in aqueous 0.4 M acetate buffer solutions of pH between 3.5 and 5.5 with added nitrate, perchlorate or halide electrolyte, in order to study the effect of the counterion on the structure and electrochemical properties of the polyaniline film. The films were characterized electrochemically by cyclic voltammetry and by impedance, and morphologically by scanning electron microscopy. Marked differences between the films are found, the highest conductivity and electrochemical response being with nitrate counterion. The films formed are generally flat and porous, with evidence of some small irregular growths. These results are compared to those obtained in sulphuric acid solution.
