| 摘 要： | 应用表面增强拉曼散射光谱(SERS)和电化学方法, 对银电极上2-氨基-5-巯基-1,3,4-噻二唑(AMT)和植酸钠混合自组装单层结构和缓蚀性能关系进行了研究. SERS光谱表明, 银电极表面形成AMT膜后, 再组装植酸钠分子能够弥合AMT膜的缺陷. 交流阻抗和极化曲线实验表明, 形成的混合自组装层比单一AMT自组装层表现出更好的缓蚀性能. AMT膜层的等效电路为R(Q(R(Q(RW)))); 混合膜层电路图为LR(Q(R(Q(R)))).

| Abstract: | The relationship between the structure and anticorrosive effect of the AMT/Na-salt of phytic acid mixed monolayers on a silver surface was investigated by SERS (surface enhanced Raman scattering spec-troscopy) and electrochemical methods. The results of SERS experiment showed that Na-salt of phytic acid could penetrate into AMT monolayers on the silver electrode through a self-assembling process. The electrochemical impedance spectroscopy indicated that the anticorrosive effect of the AMT/Na-salt of phytic ... |
