Abstract The corrosion inhibition performance of the Schiff self-assembled film (SAM) in 3.5% NaCl solution was examined by static weight loss, pola-rization curve and electrochemical impedance spectroscopy (EIS). Two factors of concentration and time were studied, respectively. The experiment result expresses when the concentration is 15 mmol/L, the assembly time is 14 h, the corrosion inhibition efficiency is up to 99.89%. Scanning electron microscope (SEM) and atomic force microscopy (AFM) analysis show that the areatus substance form on copper surface. Roman spectroscopy (Raman) analysis reveals that corrosion inhibitors adsorb vertically on the metal surface through the imidazole ring and C=N bond. Optical contact Angle (OCA) represent that corrosion inhibitor is not easily infiltrated.

Key words： Schiff base self-assembled film Raman spectrum atomic force microscope
