摘要： 利用界面流变仪研究了α-烯烃磺酸钠(AOS)和非离子Gemini表面活性剂(DWS1)的表面扩张性质。实验结果表明，AOS和DWS1的表面扩张参数随着振动频率增加而增加。随着振幅增加，AOS的表面扩张参数先增加，当振幅达到气泡面积8%后趋于平稳；但DWS1的表面扩张参数在振幅较大处，出现缓慢降低。随着温度升高，AOS和DWS1的表面扩张参数降低。AOS和DWS1的表面扩张参数随浓度增加，在质量分数0.002 2%附近出现极大值，而后逐渐降低，趋于平稳。AOS的表面扩张性质以弹性为主，DWS1的表面扩张性质以黏性为主。DWS1的表面扩张参数明显大于AOS。

Abstract: The surface dilational properties of alpha olefin sulfonate sodium (AOS) and non-ionic gemini surfactant (DWS1) were researched by interface rheometry. Results showed that surface dilational parameters of AOS and DWS1 increased with frequency increasing. As amplitude added, the surface dilational parameters of AOS first increased, and stabilized when amplitude reached to 8% of bubble area. But the surface dilational parameters of DWS1 decreased slowly at high amplitude. The surface dilational parameters of AOS and DWS1 reduced as temperature increasing. The surface dilational parameters of AOS and DWS1 increased as concentration increasing, reaching their maximum at 0.002 2% mass concentration, then reduced as concentration continued increasing, and finally stabilized. DWS1 surface dilational property was mainly viscosity, while AOS surface dilational property was mainly elasticity. The surface dilational parameters of DWS1 were significantly larger than those of AOS.
