The paper reviews the effect of the surface composition on forces within aqueous foam and wetting films. In both types of films the charge of the air/water interface is varied by different surfactants. In wetting films the charge and the hydrophobicity of the solid substrate is changed by polymer coatings. The addition of polymers to foam films leads to the formation of surface active polymer/surfactant complexes or to depletion near the interfaces. The dissolution of polyelectrolytes within the film bulk can lead to structural forces. The selection of studies is made with respect to two questions: (1) What is the reason for charges at the air/water interface and (2) what is the mechanism of long-range hydrophobic interaction?
本文综述了表面组成对水基泡沫和湿膜内作用力的影响。在这两种类型的膜中，不同的表面活性剂会改变空气/水界面的电荷。在湿膜中，聚合物涂层会改变固体基质的电荷和疏水性。向泡沫膜中添加聚合物会导致形成表面活性聚合物/表面活性剂复合物或在界面附近产生耗尽效应。聚电解质在膜主体内的溶解会导致结构力。研究的选择基于两个问题：（1）空气/水界面电荷产生的原因是什么？（2）长程疏水相互作用的机制是什么？
