随着人们对于离子液体参与自组装行为的重视,表面活性剂在其中构建溶致液晶的研究日益深入.选择离子液体作为组装介质,可将其优良特性引入到溶致液晶中,从而达到改善体系性质、扩展其应用范围的目的.本文总结了阳离子季铵盐类表面活性剂(常规单链、双链及Gemini型)、非离子表面活性剂(烷基聚氧乙醚类及植物甾醇类)及Pluronic双亲嵌段共聚物等在离子液体中自组装构建溶致液晶行为的研究进展,用可以反映溶剂内聚能密度的Gordon参数,对不同离子液体中形成溶致液晶的差异进行了分析,并对该领域的发展趋势进行了展望.
As people pay more attention to the self-assembly behavior of ionic liquids, the research on the construction of lyotropic liquid crystals by surfactants has become more and more in depth.Selecting ionic liquid as the assembly medium can introduce its excellent properties into lyotropic liquid crystals to improve the system Nature and extend the scope of its application.This paper summarizes the cationic quaternary ammonium surfactants (conventional single-chain, double-stranded and Gemini type), nonionic surfactants (alkyl polyoxyethylether and phytosterols) and Pluronic amphiphilic block copolymer self-assembled into ionic liquid in the construction of lyotropic liquid crystal research progress, with solvent can reflect the cohesive energy density of Gordon parameters of different ionic liquids in the formation of lyotropic liquid crystal were analyzed and The development trend in this area is prospected.
