The corrosion protection efficacy of electrochemically synthesized poly(2-aminobenzenesulphonic acid) (P2ABSA) on carbon steel in 1.0 M HCl was investigated by electrochemical impedance spectroscopy, Tafel polarisation, scanning electron microscopy (SEM) and FT-IR spectral studies. The polymeric coating was prepared on the steel surface using cyclic voltammetry. Investigations established that P2ABSA effectively prevent the metal dissolution in HCl medium. Polarisation studies revealed that this polymer hinder both anodic and cathodic process of corrosion appreciably. The structures of the chemically and electrochemically synthesised polymers were compared using IR spectroscopy. Morphology of the steel surface confirmed the intact response of P2ABSA on steel surface treated with HCl. [ABSTRACT FROM AUTHOR] |
