Notes:
The Self-assembled monolayers (SAMs) of Schiff base had been formed on oxidizedsurfaces of copper. Schiff base used in this paper is N-2-hydroxyphenyl-(3-methoxy-salicylidenimine), designated V-bso. X-ray photoelectron spectroscopy (XPS),polarization curves, electrochemistry impedance spectroscopy (EIS) and the interface capacitancemeasurements have been employed to investigate the structure, formation and composition of thesemonolayers. XPS analysis show that the valence of the copper in the surface films is +2. Thepolarization curves and the EIS results indicate that the films of CuO, V-bso, and V-bso modifiedoxidized copper all have good corrosion inhibition efficiency. The IE of the V-bso modified oxidizedcopper is higher than that of the V-bso modified copper and the oxidized copper layer, just becausethe former has two layers. The results of the interface capacitance show that the self-assemble films ofthe V-bso on the oxidized copper surface have good potential stability
