Tóm tắt

The aim of this work is to study the inhibition effect of water-soluble polyaniline (sulphonate polyaniline) on the corrosion of carbon steel in neutral solutions. The effect on the inhibition efficiency of concentration, temperature has been studied systematically by mass-loss method and by electrochemical measurements. All these methods confirmed that the inhibition efficiency of sulphonate polyaniline increases in increasing its concentration, but decreases in increasing temperature. The studies of potentiodynamic polarization and electrochemical impedance spectroscopy reveal that sulphonate polyaniline acts as an anodic inhibitor.
