An Electrochemical Study of Homopolymer, Copolymer and Composite Electrodes of Polypyrrole and Polycarbazoles

Copolymer and composites of pyrrole with carbazole were synthesized on a platin substrate and an electrochemical study of polymeric films was performed. The characterization of homopolymer, copolymer and composite films was performed by electrochemical methods (i.e., polarization curves and cyclovoItammetric measurements), morphological and elemental analyses, solid-state conductivity measurements and spectrophotometric methods comparatively. The reversibility of electrodes was checked by ferrocene in nonaqueous media. The stability of films was also tested both with corrosion and residual discharge capacity measurements in acidic aqueous solution.
