Abstract: The applications of interfacial 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.

Key words: Macromolecule, Surfactant, Interfacial dilational rheology, Interaction
