摘要：
Ionic liquids (ILs) attracted great attention as green corrosion inhibitors for steel in aggressive environments. The present work synthesize new IL using chitosan through amidation and quaternization reaction with oleic acid and p-toluene sulfonic acid, respectively. The chemical structure of the prepared polymeric ionic liquid was investigated using NMR analysis. The corrosion inhibitive effect of the prepared polymeric ionic liquid on steel corrosion in acid chloride solution was studied using different electrochemical techniques. Potentiodynamic polarization data revealed that the prepared ionic liquid reduces both dissolution and hydrogen evolution corrosion reactions. Impedance technique 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 the steel surfaces.
