Abstract

In this work the electropolymerization processes of a poly (aniline-o-anisidine) copolymer (PAOA) on the surface of mild steel and its anticorrosion properties were studied. Electrochemical polymerization was carried out in a 0.3 M solution of H2C2O4 by cyclic voltammetry. Morphological and elemental analysis of the coatings was carried out using X-ray scanning electron microscopy. It was observed that the polarization of the steel electrode in solution of oxalic acid results in passivation of its surface via the formation of iron oxalate (Fe2C2O4). The protective ability of the polymer layer was determined by linear polarization at different exposures in 3.5% NaCl solution. According to the results, the protective effect of the obtained polymer was 82.73% at 120 min exposure in an aggressive environment. There is a decreasing of the protective functions of the polymer layer as a result of its destruction.
