摘要: 应用超分子组装技术将含硫和含氮的双亲性金属缓蚀剂有序单分子膜按设计方式修饰在碳钢表面。探讨了在有序的单分子膜内缓蚀剂分子的排列对碳钢在硫酸中腐蚀的抑制作用,深入讨论了缓蚀剂单分子膜对碳钢腐蚀过程的抑制机理。研究发现:在单分子膜中,水合氢离子传递的离子通道强烈地依赖于缓蚀剂分子的排列方式。

Abstract: Ordered monolayers of S- and N-containing amphipathic corrosion inhibitors were depoitod onto the surfaces of carbon steel electrode with super-molecular assembly technique. The effect of molecular aggregation of monolayers on carbon steel corrosion in 0. 05 mol dl ̄(-3)H_2SO_4 and the mechanisms of these inhibitors were discussed in details. It was found that the transport of hydrated hydrogen ion to the surface of steel depends strongly on the inhibitor molecular aggregation in the monolayers.

Key words: Super-molecular assembly, LB monolayer, Metal corrosion inhibitor, Corrosion
