The effect of the presence of a charged thin gel layer on the electrode surface on mass transport of electroactive species of opposite charge was investigated. The layer was deposited using the electrochemically-induced free-radical polymerization method. The ferrocenyltrimethylammonium cation (FcN⁺) served as the electroactive probe. Ionic accumulation of the anodic electrode product was observed in experiments with normal sized electrodes. Microelectrodes were used without supporting electrolyte to study the contribution of migration to the overall mass transport to the modified surface.

受静电相互作用影响的离子物质的扩散和迁移传输，其中静电相互作用与附着在电极表面的带相反电荷的水凝胶层

研究了电极表面上带电薄凝胶层的存在对相反电荷的电活性物质传质的影响。使用电化学诱导的自由基聚合方法沉积该层。二茂铁基三甲基铵阳离子（FcN ⁺）用作电活性探针。在使用常规尺寸电极的实验中，观察到了阳极电极产物的离子积累。使用不支持电解质的微电极来研究迁移对整体质量向改性表面传输的贡献。
