We present an extension to the Poisson-Boltzmann model where the dipolar features of solvent molecules are taken explicitly into account. The formulation is derived at mean-field level and can be extended to any order in a systematic expansion. It is applied to a two-plate system with oppositely charged surfaces. The ion distribution and profiles in the dipolar order parameter are calculated and can result in a large correction to the interplate pressure.
我们提出了泊松-玻尔兹曼模型的一个扩展,其中明确考虑了溶剂分子的偶极特征。该公式是在平均场水平上推导出来的,并且可以在系统展开中扩展到任意阶次。它被应用于具有相反电荷表面的双板系统。计算了离子分布和偶极序参量的分布,这可能会对板间压力产生很大的修正。
