泡沫液膜中聚合物与表面活性剂相互作用的研究进展

加入聚合物对泡沫液膜的作用是涉及众多工业应用的重要问题。讨论了聚合物-表面活性剂复合泡沫体系中影响液膜厚度和稳定性的因素。聚合物的加入对泡沫液膜稳定性的影响取决于所形成的液膜种类(普通黑膜或牛顿黑膜)。聚合物的加入在液膜中形成构造应力。加入的聚合物与表面活性剂作用形成具有表面活性的复合物,或富集于液膜界面处,使液膜稳定性大大增强。

Research Progress in Interaction Between Polymer and Surfactant in Foam Film

The effect of adding polymer to foam film on the foam film is an important question, which can be used in heightening the recovery efficiency of oil fields.The relationships of the surfactant-polymer combination with thickness and stability of the film are discussed.The effect of adding polyelectrolyte on the stability of the foam films is highly related to the type of the final film (common black film or Newton black film).The dissolution of the polyelectrolytes within the film bulk can lead to structural stress.The addition of the polymers to the foam films can result in the formation of surface active polymer-surfactant complexes,which can enhance the film stability.
