在铜表面形成精氨酸(Arg)自组装单分子膜。用电化学阻抗谱和极化技术研究了Arg自组装膜在0.5M盐酸溶液中的防腐性能。结果表明，精氨酸自组装膜的保护作用有限。自组装时间越长，自组装效率越高，6h时达到最大值；在含Arg溶液中加入碘离子后，混合自组装膜的缓蚀能力显著提高。在AM1量子化学计算的基础上，讨论了Arg自组装膜的腐蚀防护机理。
Self-assembled monolayers (SAMs) of arginine (Arg) were formed on copper surface. The corrosion protection properties of the Arg SAMs were examined by electrochemical impedance spectroscopy and polarization techniques in 0.5 M HCl solution. The results show that Arg SAMs have limited protection effect. The protective efficiency increased with an increase of self-assembly time and reached maximum protection at 6 h. When iodide ion was added to the Arg-containing solution, the ability of the corrosion inhibition of the mixed SAMs improved significantly. The corrosion protection mechanism of Arg SAMs is discussed based on AM1 quantum-chemical calculations.
