摘要
采用分子模拟的方法研究表面活性剂的泡沫生成能力,以界面形成能作为考察泡沫体系中液膜界面积的量化依据,研究了泡沫液膜厚度、表面活性剂分子界面密度以及表面活性剂类型对泡沫液膜界面形成能计算的影响.通过与实验结果相对应,建立了界面形成能和泡沫生成能力之间的联系.
Foam formation ability of surfactants has been investigated with Molecular Simulation method. As the denotation of foam formation ability, interface formation energy （IFE） which is corresponded to the amount of foam film area of different systems have been investigated by considering the variation of film thickness, interfacial density and surfactant type. According to the results of experiment, the relationship between interface formation energy and foam formation ability has been built.
