摘要：

Polyaniline/polypyrrole composite coatings on low carbon steel were deposited by a potentiostatic method using oxalic acid as the electrolyte. The applied potential and feed ratio of monomers (aniline and pyrrole) were varied and the reactions were performed under aqueous conditions. It was found that a passive layer of iron (II) oxalate is formed before coating formation begins. Coatings were characterised using infrared spectroscopy, and the formation of composites was confirmed by the presence of polyaniline and polypyrrole peaks. Formation of composites was further corroborated by comparison of voltammograms from composites and homopolymers and by scanning electron microscopy.
