论文摘要
基于由电荷调节的宏观离子和简单盐离子组成的电解质的集体描述，我们分析了它们在整体中的平衡电荷状态及其在外部电气表面附近的行为。电解质沐浴溶液中移动宏观离子的平均场公式扩展到包括关联/解离位点之间的相互作用。我们证明，盐的临界浓度高于临界浓度，并且与临界胶束浓度相似，在集中电荷状态的非平凡分布中。这种电荷状态最终可以基于电荷调节导致液态液相分离。
Based on a collective description of electrolytes composed of charge-regulated macro-ions and simple salt ions, we analyze their equilibrium charge state in the bulk and their behavior in the vicinity of an external electrified surface. The mean-field formulation of mobile macro-ions in an electrolyte bathing solution is extended to include interactions between association/dissociation sites. We demonstrate that above a critical concentration of salt, and similar to the critical micelle concentration, a non-trivial distribution of charge states sets in. Such a charge state can eventually lead to a liquid-liquid phase separation based on charge regulation.
