Impedance and Voltammetric Studies of Electrogenerated Polyaniline Conducting Films

Abstract

Polyaniline films were electrochemically synthesized from three acidic media; sulfuric, hydrochloric and perchloric acids. Cyclic voltammetry was used in the electrosynthesis and the effects of voltammetric parameters on the properties of the films were investigated. The main tool of film characterization was impedance spectroscopy. Semiautomated plotting of three-dimensional Argand diagrams with potential parameter was used for synoptic view of the system and nonlinear least square data fitting was used for rigorous treatment. Charge storage capacity, resistance and changes in constant phase element parameters are analyzed in relation to the use of three acidic media.
