摘要 采用动电位极化与交流阻抗谱方法,研究了电解铜箔经不同剂量的硅烷偶联剂γ-APT表面硅烷化处理后在3.5%NaCl溶液中的腐蚀防护效果.实验通过改变硅烷与乙醇、水为溶剂配比以及溶液pH值、固化温度、固化时间等因素,探索自组装形成的有机膜对铜箔影响效果.结果表明:γ-APT自组装膜具有良好的耐腐蚀性能,其中含量为2.0%,pH值为5的γ-APT硅烷液涂覆铜箔经100℃固化1h自组装形成的有机膜防腐效果较优. We studied the electrolytic copper foil's corrosion protection effect afterγ-APT surface silylation treatment by the electrodynamic polarization and electrochemical impedance spectroscopy(EIS)analysis.The experiment was carried out in 3.5%NaCl solution with various dosages of silane coupling agent.We systematically investigated the corrosion resistance of self-assembled organic film on copper foil under different conditions by changing the ratio of silane to ethanol and water,pH value,curing temperature and curing time.The results reveal that the self-assembledγ-APT film has good corrosion resistance.The optimum technique is 2.0%γ-APT silane liquid content under pH value of 5,100℃and one hour's curing time.
