带电球形粒子分散体中的动力学过程在基础科学、技术和生物医学应用中都具有重要意义。存在大量的带电粒子系统，从纳米尺寸的电解质离子到微米尺寸的电荷稳定胶体。本文综述了浓颗粒体系线性输运系数计算理论方法的最新进展，重点是流体动力学相互作用和电动效应。考虑的传输特性是分散粘度，自我和集体扩散系数，沉降系数，和电泳迁移率和电导率的离子粒子物种在外部电场中。我们的小组的进展也进行了讨论，包括一个新的模式耦合理论方法的导电扩散和粘弹性强电解质溶液。此外，结果提出的分散体的溶剂可渗透的颗粒，和颗粒与非零流体动力学表面滑移。离子微凝胶的浓度依赖性的溶胀进行了讨论，以及一个深远的动态标度行为有关的胶体长时间到短时间的动态。
Dynamic processes in dispersions of charged spherical particles are of importance both in fundamental science, and in technical and bio-medical applications. There exists a large variety of charged-particles systems, ranging from nanometer-sized electrolyte ions to micron-sized charge-stabilized colloids. We review recent advances in theoretical methods for the calculation of linear transport coefficients in concentrated particulate systems, with the focus on hydrodynamic interactions and electrokinetic effects. Considered transport properties are the dispersion viscosity, self- and collective diffusion coefficients, sedimentation coefficients, and electrophoretic mobilities and conductivities of ionic particle species in an external electric field. Advances by our group are also discussed, including a novel mode-coupling-theory method for conduction-diffusion and viscoelastic properties of strong electrolyte solutions. Furthermore, results are presented for dispersions of solvent-permeable particles, and particles with non-zero hydrodynamic surface slip. The concentration-dependent swelling of ionic microgels is discussed, as well as a far-reaching dynamic scaling behavior relating colloidal long- to short-time dynamics.
