摘要：
A study has been made on the corrosion protection performance of tungstate doped polyaniline containing vinyl coating on steel. The tungstate doped polyaniline was chemically synthesized and characterized by FTIR, XRD, UV-VIS and TGA studies. The corrosion protection performance of vinyl coating containing tungstate doped polyaniline on steel was assessed in 3% NaCI by electrochemical impedance studies (EIS). The coating has been found to offer protection more than 60 days in salt spray and immersion in 3% NaCl FTIR studies have shown that the formation of iron-tungstate complex along with the passive film on steel.
