| 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 expoun- ded.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. |
