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. Molecular modeling method was used to study the foam formation ability of surfactant. The interfacial formation can be used as a quantitative basis to investigate the liquid membrane interface in the foam system. The effects of foam liquid film thickness, surfactant molecular interface density and surfactant type on Foam liquid membrane interface formation can calculate the impact.According to the experimental results, the relationship between the interface formation energy and foam generation ability is established.
