Electrodeposition of polypyrrole/carboxymethyl cellulose on platinum and indium tin oxide

Abstract

The paper presents information on the synthesis and properties of a composite material consisting of an electronically conducting polymer and a polyanion. This kind of materials are of current interest. Polypyrrole- carboxymethyl cellulose composite have been studied on two different substrates: platinum and indium tin oxide. Electrochemical, SEM, and U.V-visible techniques have been used. The mechanism in both electrodes seem to be the same, but the morphology was quite different with the same electrodeposition conditions. Dendritycal growth on indium tin oxide in special conditions has been observed.
