| Description |
Electrosynthesis of polyaniline–molybdate (PANI–MoO42−) on mild steel was achieved in oxalic acid medium using cyclic voltammetry technique. Adherent and homogeneous PANI–MoO4
2− coating was obtained. The corrosion behavior of steel with PANI–MoO4 2− coatings in 1% NaCl solutions was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The
coating was characterized by SEM, XPS, EDAX and FTIR. The self-healing ability of PANI–MoO4 2− coating
was confirmed by SVET technique. It has been found that the PANI–MoO42− coating is able to offer higher corrosion protection in comparison to that of pure PANI coating due to inhibitive nature of molybdate ions
