The Formation and the Electrochemical Behaviors of Self-assembling Lipid Membranes Supported by Platinum

摘要/Abstract

摘要:

利用超声清洗铂电极表面的方法制备了铂支撑的自组装类脂膜。应用电化学交流阻抗谱及循环伏安方法测定了浸有成膜液的铂电极在0.1mol/lKCl中浸泡不同时间后的电化学行为。由交流阻抗谱测得所形成的铂支撑双层类脂膜的电容值为0.51μFcm-2,电阻为1.3×109Ω。在(-0.1~0.5)V的研究范围内,铁氰化钾/亚铁氰化钾的氧化还原峰消失,表明所形成的类脂膜没有明显的缺陷。

Abstract:

A new method for preparing Pt-supported lipid membranes on Pt electrode cleaned by ultrasound is reported. The cyclic voltammograms and electrochemical impedance spectroscopy of the self-assembling lipid membranes on Pt in the solution of 0. 1MKCl at different time are determined. The capacitance and the resistance of lipid membranes are 0. 51μFcm-2and 1. 3×109Ω determined by ac impedanre measurement.It is also found that the ptatinum-supported lipid membranes prepared by this new method has not apparently defeacts because there is no redox peaks int he solution of Fe(CN)3-6/Fe(CN)4-6.
