The polymerization of pyrrole was carried out in an aqueous solution of oxalic acid on platinum anode at several current densities. Polymer weights formed on the anode increase linearly with the time of electrolysis at a fixed current level. The polymer formation occurs only on the anode and not in the body of the solution because the anolyte remains completely clear during the course of polymerization. The cyclic voltammograms of polypyrrole film made electrochemically were examined in the presence and absence of pyrrole in the aqueous solution of oxalic acid. Cyclic voltammetry studies suggest that the polymeric film suffers no degradation

Abstract


The polymerization of pyrrole was carried out in an aqueous solution of oxalic acid on platinum anode at several current densities. Polymer weights formed on the anode increase linearly with the time of electrolysis at a fixed current level. The polymer formation occurs only on the anode and not in the body of the solution because the anolyte remains completely clear during the course of polymerization. The cyclic voltammograms of polypyrrole film made electrochemically were examined in the presence and absence of pyrrole in the aqueous solution of oxalic acid. Cyclic voltammetry studies suggest that the polymeric film suffers no degradation
