我们考虑了胶束物理性质的离子专一性的起源。溶液中的离子具有与周围水不同的极化率。超额极化率对于不同的离子是不同的，并引起朝向或远离界面的离子特定的色散力。结果表明，离子色散力对胶束的自洽势、离子分布和每个头基的表面吸附过剩有重要影响。
We consider the origin of the ion specificity found for the physical properties of micelles. Ions in solution have a polarizability different from that of the surrounding water. The excess polarizability is different for different ions and gives rise to ion specific dispersion forces toward, or away from, interfaces. We show that ionic dispersion forces have important influences on self-consistent potentials, ion distributions, and surface adsorption excess per headgroup on micelles.
