Polymerization of Aniline on Mild Steel and its Corrosion Protection

Abstract:

The production of polyaniline films on mild steel from sulfuric acid was carried out using cyclic voltammetry. Corrosion protection of the coating was observed in 3.5% NaCl using electrochemical impedance spectroscopy, (EIS) and potentiodynamic polarization measurements. Results showed that the polyaniline layer has the potential to protect mild steel by stabilizing the oxide layer formed on the steel surface and thus prevent the metal dissolution process.
