摘要
微乳液一般是指两种互不相溶的液体(极性相:一般为水;非极性相:一般为有机溶剂),在表面活性剂作用下形成的均一透明的热力学稳定体系,已广泛应用于材料制备、化学合成等领域.离子液体是熔点低于100℃,完全由离子组成的一类物质,作为一种"绿色溶剂",具有诸多优异的物理化学性质,又被称为"可设计型溶剂".本文综述了离子液体作为极性相、非极性相,甚至表面活性剂,构筑的一类微乳液――离子液微乳液,重点介绍了其物理化学性质的研究进展,并展望了发展趋势.
Microemulsions are transparent and thermodynamically stable dispersions of two immiscible solvents （usually water as the polar phase and oil as the apolar phase） stabilized by a surfactant,which have been extensively applied in many fields such as material synthesis and chemical reactions.Ionic liquids,combinations of cations and anions with the melting point lower than 100 °C,are novel environmentally benign ＂green solvents＂ and ＂designer solvents＂ and have amazing physicochemical properties.This paper focuses on the physicochemical properties of a new type of microemulsions based on ionic liquids,ionic liquid microemulsions,in which ionic liquids serve as the polar phase,the apolar phase,or the surfactant.The trend for future research is also prospected.
