The mild steel (MS) corrosion inhibitive performance of benzene derived Schiff’s base in 1 M HCl solution was investigated using weight loss and potentiodynamic polarization measurements. The effect of temperature on the corrosion performance in the presence of inhibitor was evaluated between the range of 303 K and 333 K. The inhibition efficiency was observed to increase with an increase in concentration and temperature. The studied inhibitor follows Langmuir adsorption isotherm by physisorption process. The surface morphological studies of the protective layer on the MS surface specified the adsorption of Schiff’s base molecules on metal surface. In the present research, a novel Schiff’s base corrosion inhibitor was synthesized, and some quantum chemcial calculations were performed to comprehend the mechanism of inhibition.
