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)))).
Surface-enhanced Raman scattering spectroscopy (SERS) and electrochemical methods were used to investigate the effect of the mixed self-assembled monolayer structure of 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) SERS spectra show that the formation of AMT film on the silver electrode surface after the assembly of sodium phytate to bridge the defects of the AMT film.An impedance and polarization curve experiments show that the formation of hybrid self-assembled layer than the single AMT The self-assembled layer shows better corrosion inhibition performance.The equivalent circuit of AMT layer is R (Q (R (Q (RW)))); )).
