积分方程理论与桥梁功能纳入封闭方程分析如何溶剂诱导的表面之间的相互作用的影响，溶质除了溶剂。溶剂粒子通过硬核加吸引势相互作用。表面是疏溶剂性或亲溶剂性的，溶质具有相当高的疏溶剂性或亲溶剂性：总共考虑了表面和溶质性质的四种组合。溶质添加总是导致向下移动，在一个更有吸引力的方向上的移动，表面相互作用（除了在非常小的表面分离）。随着溶质疏溶剂性或亲溶剂性增加以及溶质浓度变高，该移位变得更加显著。总的来说，溶质的影响是最小的溶质时，既不是疏溶剂，也不是亲溶剂。通过与溶剂-溶质混合物结构的相互作用，详细讨论了这种位移的物理起源。
Integral equation theories with bridge functions incorporated in the closure equations are employed to analyze how the solvent-induced interaction between surfaces is influenced by solute addition to the solvent. The solvent particles interact through a hard-core plus attractive potential. The surfaces are solvophobic or solvophilic, and the solute has rather high solvophobicity or solvophilicity: A total of four combinations of the surface and solute properties are considered. The solute addition always leads to a downward shift, a shift in a more attractive direction, of the surface interaction (except at very small surface separations). The shift becomes more pronounced as the solute solvophobicity or solvophilicity increases and the solute concentration becomes higher. Overall, the solute effects are the smallest when the solute is neither solvophobic nor solvophilic. The physical origins of the shift are discussed in detail by relating the interaction to the structure of the solvent–solute mixture co...
