| 摘 要： | 采用界面张力弛豫技术研究了不对称Gemini表面活性剂C12COONa-p-C9SO3Na、部分水解聚丙烯酰胺Mo-4000和疏水缔合水溶性聚丙烯酰胺(HMPAM)等驱油体系化学剂在癸烷/水界面上的扩张流变性质,考察了不同离子强度和不同类型电解质对体系界面流变性质的影响,计算得到界面扩张弹性模量和粘性模量的全频率谱,并通过归一化方法(Cole-cole图)探讨了界面吸附膜的弛豫过程.研究发现,界面膜内分子重排和界面与体相间分子扩散交换是影响膜性质的主要弛豫过程.表面活性剂体相浓度增大有利于界面分子重排过程,而低频有利于扩散交换过程;不同结构聚合物以及不同离子强度和不同类型电解质对表面活性剂吸附膜有不同的影响. |
