Electropolymerization of pyrrole on steel substrate was carried out in aqueous oxalate solutions in the presence of amines. Triethylamine and allyamine were the amines used in this study. The electropolymerization process of pyrrole in acidic medium was found to be different from that in alkaline medium. In acidic medium, the reactions were characterized by an induction period while no such period was observed in alkaline medium. Our results show that the pH of the reaction medium and the applied current density had a great influence on the induction time. Effects of triethylamine and allyamine on the electropolymerization process of pyrrole were very similar. The composition of the coatings was studied by FTIR and elemental analysis. The coatings formed in different medium had a similar composition. Smooth, uniform, strongly adherent coatings could be formed on the steel substrate by proper choice of the reaction parameters.
