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.

Key words: polymeric coating, corrosion protection, mechanism, coating/metal interface, self-assembled monolayer
