| 摘 要： | 用γ-氨丙基三甲氧基硅烷(γ-APS)溶液对铜箔表面硅烷化处理，采用动电位极化和电化学交流阻抗研究不同pH的γ-氨丙基三甲氧基硅烷溶液自组装铜箔电极在0.1 mol.L-1NaCl溶液的腐蚀防护效果，采用扫描电子显微镜观察γ-氨丙基三甲氧基硅烷自组装膜的表面形貌.结果表明，γ-氨丙基三甲氧基硅烷自组装铜箔有较好的腐蚀防护效果，其中pH=7的γ-氨丙基三甲氧基硅烷溶液自组装膜的抗腐蚀效果最佳.

| Abstract: | Copper foil specimens were immersed in hydro-alcoholic solution of 3-amino-propyl-trimethoxy-silane(γ-APS) to prepare a protective self-assembled siloxane membrane on the surface.Potentiodynamic polarization and electrochemical impedance spectroscopic tests were performed in 0.1 mol·L-1 NaCl to evaluate the effects of the self-assembled siloxane membranes prepared at different pH of γ-APS on corrosion of copper foil.The surface morphology of siloxane membrane was studied by SEM.Experimental results revealed that the γ-APS self-assembled siloxane membranes effectively inhibited the corrosion of copper foil and the optimum anti-corrosion effect was found when the pH value of the silane solution was 7. |
