【摘要】 用(E)-3-(咪唑基-1-甲基)肉桂酸分子在铁表面形成自组装膜,并用电化学阻抗谱和极化曲线研究不同组装时间对自组装膜缓蚀效果的影响,并运用量子化学计算初步探讨(E)-3-(咪唑基-1-甲基)肉桂酸在铁表面的缓蚀机理.结果表明,(E)-3-(咪唑基-1-甲基)肉桂酸分子能自发吸附在铁表面形成自组装膜,随着组装时间的增加,自组装膜对铁的缓蚀效率也相应增加.更多还原

【Abstract】 (E)-3-(4-((1H-imidazol-1-yl)methyl)Phenyl)acrylic acid was used to form self-assembled films on iron surface.The protection abilities of the films against iron corrosion were investigated using electrochemical impedance spectroscopy and polarization curves techniques.Quantum chemical calculations were used to explain the experimental results to some extent.The electrochemical measurements results indicate that films of(E)-3-(4-((1H-imidazol-1-yl)methyl)Phenyl)acrylic acid can from on the iron surface spontaneously and longer immersion time of the iron electrode in the solution will result in stronger inhibition ability of the films.更多还原
