Surfactant molecules in a non-polar liquid form charged and uncharged inverse micelles. When a potential difference is applied over the mixture, the charged inverse micelles drift towards the electrode with the opposite polarity. The motion of charges is associated with a transient current, which can be measured in an external circuit. In this paper, transient currents and steady state charge densities are described analytically in different ranges of parameter values (applied voltage, charge density, device thickness, mobility,...). The generation of additional charged inverse micelles and the electrophoretic motion of colloidal particles in the mixture is modelled and measured experimentally.
在非极性液体中，表面活性剂分子形成带电和不带电的反胶束。当在混合物上施加电势差时，带电荷的反胶束会向具有相反极性的电极漂移。电荷的运动与瞬态电流相关联，该电流可以在外部电路中测量。在本文中，分析了不同参数值范围（施加电压、电荷密度、器件厚度、迁移率等）下的瞬态电流和稳态电荷密度。还对混合物中额外带电反胶束的产生和胶体粒子的电泳运动进行了建模和实验测量。
