水相和特殊介质中有序聚集体的结构、性质和应用(Ⅰ)——表面活性剂在水相和离子液体中的有序聚集体

Structures,properties and applications of ordered aggregate in aqueous phase and ionic liquids(I)——Ordered aggregate formed by surfactant in aqueous phase and ionic liquids

首先介绍了表面活性剂溶液性质和各种聚集体结构,其中包括胶束、微乳液、囊泡和溶致液晶等,以及聚集规则———临界堆积参数等。同时介绍了表面活性剂在离子液体中形成的各种典型有序聚集结构,特别阐明在室温下表面活性剂在水溶液和离子液体中聚集形成的有序聚集体的异同点;另外还介绍了利用表面活性剂在离子液体中形成的聚集体作为模板制备微纳颗粒。

Properties of surfactants in aqueous phase and structures of various aggregates including micelles, vesicles, microemulsions and lyotropic liquid crystals as well as the rule of aggregation and the critical molecular packing parameters of the aggregates et al were presented. Various typical ordered aggregate structures formed by surfactants in ionic liquids were introduced. Particularly, the common point and different points between ordered aggregates formed by surfactants in aqueous solution and ionic liquids were clarified. Besides, the use of aggregates formed by surfactants in ionic liquids as template for preparing micro - particles and nano-particles were described.
