摘要

Ionic liquids ( ILs) attracted great attention as green corrosion inhibitors for steel in aggressiveenvironments. The present work synthesize new IL using chitosan through amidation andquaternization reaction with oleic acid and p-toluene sulfonic acid, respectively. The chemicalstructure of the prepared polymeric ionic liquid was investigated using NMR analysis. The corrosioninhibitive effect of the prepared polymeric ionic liquid on steel corrosion in acid chloride solution wasstudied using different electrochemical techniques. Potentiodynamic polarization data revealed that theprepared ionic liquid reduces both dissolution and hydrogen evolution corrosion reactions. Impedancetechnique shows one capacitive loop that indicated the charge-transfer process of the steel corrosion.Langmuir isotherms found to fit properly the adsorption of the prepared polymeric ionic liquid over thesteel surfaces.
