摘要

应用循环伏安法,以铜离子为探针研究硬脂酸钠在油/水界面上的自组装过程.结果表明,硬脂酸钠在蓖麻油/水界面上自组装,经4种聚集状态而达到完整的有序单层膜.Cu2+离子在涂蓖麻油电极上的氧化是完全受吸附控制,而在表面活性剂硬脂酸钠自组装膜的油/水界面上,则其电极过程受扩散和吸附两者混合控制.循环伏安测试给出,峰电流ip随扫描速率v变化的拟合方程为:ip=9.214?3.889v1/2+0.5809v,r=0.9978.

Abstract

The self-assembled monolayers of sodium stearate surfactant on oil/water interface was investigated by CV with copper ion as probe.The self-assembling process includes four stages,and forms a stable assembly.The electrochemical oxidation of copper ion at assembled surface is a combine controlled process both surface and diffusion with regression equation as i_(p) = 9.214-3.889 v~(1/2) +0.5809v,r=0.9978,compared with the oil covered bared electrode,it is a complete surface controlled.
