| 摘 要： | 关于表面活性剂溶液中预胶束的形成问题已有不少报道［’－‘］．预胶束是表面活性剂溶液在浓度很稀时（远小于其临界胶束浓度（CMC》、表面活性分子所形成的一种集合体·由于一般的物理化学方法对其难于捡出，因此常被研究者忽略．文献间曾指出：预胶束形成的驱动力与胶束一样，也是疏水作用所致．因此表面活性分子的链长、头部极性、溶剂性质以及添加物的引入等因素必然会影响预胶束的形成．本工作是对添加物的引入问题所作的初步研究·。作中所研究的阴离子表面活性剂有十二烷基硫酸钠（sss）·＋”烷基；Iv酸钠（5％）和十六烷基硫酸…

| Abstract: | The mechanism of premicellar formation in aqueous solution of six kinds of ionic surfactant has been studied.By the introduction of different additives in the solution of surfactants, it was observed that the factors which can iafluence the micellar formation,have the same effect on the prendcenar formation. This demonstrates that both micellar and premicellar formation processes identical mechansm. Therefore, the premicellar for mation can be considered as a precusor of Ancellar formation. |
