The rate of formation of polypyrrole coatings on stainless steel increased proportionately with the current density but increased slightly with increased pyrrole concentration. Increasing oxalic acid concentration also had no significant change in the polymerization rate. The electropolymerization potential of pyrrole decreased significantly from 1.5 to 0.8 V versus SCE when the working electrode was polished. The polymerization potential, Ep, of pyrrole, increased however, with increased current density and decreased exponentially with the initial monomer and electrolyte concentration, respectively. © 1997 John Wiley & Sons, Inc.
