摘　　要：结合本课题组的工作,较系统地总结了近年来有关界面扩张流变技术在大分子/表面活性剂混合体系研究中的应用.大量研究表明,通过分析界面扩张粘弹性数据和界面弛豫过程的特征参数可以研究界面层微观性质,从而阐明大分子/表面活性剂的相互作用机理,这对实际生产和应用具有重要的指导意义.The applications of interracial dilational rheology method in studying macromolecule/surfactant system were systematically summarized combing with our work. Many previous studies have indicated that this method can be used to probe the microcosmic property of interfacial layer. This is done by analyzing the interfacial dilational viscoelasticity and characteristic parameters of the interfacial relaxation process. The interaction mechanism between macromolecule and surfactant could thus be investigated. The method can be applied in practice.
