摘要: 研究了在金电极表面硫醇自组装膜上聚电解质多层有序膜的形成过程及其电化学特性.用紫外光谱和电化学方法对多层有序膜进行了表征.结果表明,有序膜影响着离子在膜中的穿透性,离子型电活性物质如铁氰根离子和亚甲蓝等可嵌入有序膜中.研究了多层有序膜电极的电化学特性及膜中铁氰根离子的电化学行为.

关键词: 自组装膜, 聚电解质有序膜, 表观电子扩散系数

Abstract: Amultilayer film of polycation and polyanion complex on a thiol self-assembledmonolayer at gold electrode was presented.The electrochemical characteristics was studiedby using cyclic voltammetry.Electroactive ions such as ferricyanide and MBcan be incorporated into the multilayer and the apparent electron diffusion coefficients were detemined byusing normal pulse voltammetry.

Key words: Self-assembled monolayer, Multilayer ordering film, Apparent electron diffusion coefficient
