| Abstract: | Polyaniline films are fabricated on an electrode of mixed indium and tin oxides (ITO) during the cathodic reduction of dioxygen in an aniline-containing solution. Their electrochemical properties are characterized by methods of cyclic voltammetry, faradaic impedance, and chronoamperometry. A quantitative treatment of results that are obtained by the last two methods leads to results that well agree with each other and makes it possible to reliably determine basic charge transport parameters. |
