Potentiostatic Deposition of Conducting Poly(Aniline-Co-O-Anisidine) Coating on Low Carbon Steel and its Corrosion Performance

Conducting poly(aniline-co-o-anisidine) coatings were synthesized on low carbon steel by electrochemical polymerization of aniline and o-anisidine in aqueous oxalic acid by using potentiostatic method. The characterization of these coatings were carried out by using scanning electron microscopy. The corrosion protection performance of these coatings were evaluated by using potentiodynamic polarization technique. It was found that uniform and adherent conducting poly (aniline-co-o-anisidine) coating can be obtained on low carbon steel using potentio static technique. The potentiodynamic polarization study reveals that the coating offers significant corrosion protection to low carbon steel in acidic medium.
