摘要/Abstract

摘要：

研究了不同浓度十二烷基苯磺酸钠（SDBS）溶液在气－液表面上的扩张粘弹性质,讨论了扩张模量、扩张粘度、扩张模量的相角随频率的变化规律,实验结果表明,其表面膜的微观弛豫过程主要受扩散弛豫类型控制.此外,本文还讨论了温度、浓度等因素对SDBS表面扩张性质的影响,研究了它们的内在联系.

Abstract: The dilational viscoelasticity properties of gas-water interface of SDBS were investigated. The dependence of dilational modulus, dilational viscosity and phase angle on dilational frequency was expounded. The results showed that the microscopic relaxation model of the surface film was decided by diffusion-control model. Besides, the influence of temperature and concentration to the interfacial dilational properties of SDBS was also discussed, and the intrinsic relation between them was studied.
