Combined Electrochemical and Radiotracer Study on the Ionic Charge Transport Coupled to Electron Transfer and Ionic Equilibria in Electroactive Polymer Films on Electrodes

Abstract

A combination of electrochemical and radiotracer methods offers a unique possibility of studying the motion of counter‐ and co‐ions during electrochemical transformations occurring in a polymer film. In addition, information can be obtained about the embedding of electrolytes during electropolymerization penetration of electrolytes into the films prepared by solvent‐evaporation procedures, the ion‐exchange behavior, and the mechanism of the redox processes. Results on poly/vinyl ferrocene/tetracyanoquinodimethane polyester, polypyrrole, and polyaniline are described.
