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 degradationKeywords

The polymerization of thiophene was studied using BF3O(C2H5)2 as a supporting electrolyte at a platinum electrode to obtain conducting polythiophene. The result shows that the electrical conductivity is relatively higher in acetonitrile compare to that obtained 1,2-dichloroethane (DCE).Polymer films formed in DCE were black floppy and brittle but those obtained in acetonitrile were smooth and flexible. The cyclic voltammetric study was also made and the result shows that polymer films are stable.Keywords

The cyclic voltammograms of polyaniline films prepared electrochemically in the aqueous solution of sulfosalicylic acid, naphthalene -2- sulfonic acid, anthraquinone-2- sulfonic acid and polyacrylic acid were examined in the range of -0.2V to 1.0VvsSCE in the presence and absence of aniline. The multiple cycled voltammograms were recorded with a number of potential scans indicating that the conducting film formed and the thickness increased with potential cycles. The multiple cycled voltammograms confirm that the film is fairly stable without any severe film degradation. The conductivities of polyaniline films prepared at a constant potential electrolysis at +0.85Vvs SCE on a platinum anode in the aqueous solution of aniline with different electrolytes were determined.Keywords
