| 摘 要： | 将铜电极浸泡在不同浓度的N,N-二甲基甲酰胺溶液中,分别制备了各种自组装膜,用交流阻抗和稳态极化曲线研究了每种自组装膜在中性NaCl溶液中对金属铜的缓蚀作用,结果表明0.1mmol/L的N,N-二甲基甲酰胺溶液的自组装膜在0.5mol/L的NaCl溶液中对铜有较好的缓蚀效果,缓蚀效率为95.97%.

| Abstract: | The N,N-Dimethylformamide self-assembled films,with different concentration,were prepared on copper electrode surface.Electrochemical impedance spectroscopy(EIS)and Potentiostatic steady-state polarization curve were performed to characterize their inhibition effects for copper in neutral NaCl solution.The results show that the self-assembled film formed in 0.1mmol/L N,N-Dimethylformamide solution has better inhibition effect for copper in 0.5 mol/L NaCl solution.The inhibition efficiency was 95.97%. |

| Keywords: | self-assembled film AC impedance steady-state polarization corrosion inhibition |
