摘要：
By formation of epoxy coating on n-dodecanethiol self-assembled monolayer on copper substrate, self-assembled monolayer was introduced between epoxy coating and copper electrode. The formation of self-assembled interfacial n-dodecanethiol monolayer and its effect on the corrosion protection of epoxy coating were evaluated using the X-ray photoelectronic spectroscopy, electrochemical impedance spectroscopy, impedance-time transition, and phase angle-time transition method. It was found that, the self-assembled interfacial monolayer can improve the corrosion protection of the epoxy coating greatly. The mechanism for the great improvement was discussed.
