摘要

Improved anticorrosion of a copper surface after being modified with methimazole (MMl) monolayers was studied by electrochemical impedance spectroscopy (EIS), and electrochemical polarization measurement. The EIS mechanism of the copper surface with mMI monolayers was in agreement with the mode of R(Q(RW))(CR), and polarization experiments exhibited the anticorrosive effect of the MMI film on the copper surface with an high efficiency of91.2%. Surface-enhanced Raman scattering (SERS) results indicated that the MMI molecule was self-assembled on the copper surface through S~6 and N~2 atoms to form monolayers in a tilted orientation, resulting in a strong interaction between the MMI molecule and the surface. An in situ electrochemical SERS experiment was conducted from 0 to -1.6 Vvs SCE for observing the stability of MMI monolayers on the copper surface.
