水可及表面积的减少驱动了两个大的疏水板在水和盐水溶液中的缔合：两个板的接触构型在所有情况下都具有最小的吉布斯能。具有与沃茨的强静电吸引力的高电荷密度离子使得腔产生过程的成本更高，如通过经典缩放粒子理论计算所确定的，并且加强成对疏水相互作用。低电荷密度的离子，由于分散相互作用而优先结合到板表面，必须被去除以达到接触构型并削弱成对的疏水相互作用。(C)2010爱思唯尔有限公司版权所有。
The decrease in water accessible surface area drives the association of two large hydrophobic plates in both water and aqueous salt solutions: the contact configuration of the two plates possesses the minimum Gibbs energy in all cases. High charge density ions, having strong electrostatic attractions with waters, render more costly the process of cavity creation, as determined by classic scaled particle theory calculations, and strengthen pairwise hydrophobic interaction. Low-charge density ions, being preferentially bound to plate surfaces due to dispersion interactions, have to be removed to arrive at the contact configuration and weaken pairwise hydrophobic interaction.
