Abstract The oleic acid imidazoline and acrylic acid imidazoline were synthesized and their structures were characterized by IR spectrum. Their inhibition behaviors for aluminium foil in 2.0 mol/L HCl solution were studied by polarization curves and electrochemical impedance methods. The influences of specific capacitance of the two imidazolines on aluminium foil for electrolytic capacitors during DC etching were investigated by capacitance measuring instrument and SEM. The results show that the two compounds were both cathodic corrosion inhibitors for aluminium foil in 2.0 mol/L HCl solution. The inhibition efficiency of acrylic acid imidazoline was better than oleic acid imidazoline. Of the etched aluminum foil, weight loss decreased, tunnel density increased and well distributed, specific capacitance increased by 25% when inhibitors added in 2.0 mol/L HCl solution.
