Progress and Developments of Researches on Interface Concerning Ionic Liquids

Abstract

It is quite important to analyze and design interface between ionic liquid and other materials due to further development of functional interface. In the present study, physicochemical properties of mixtures containing ionic liquids are discussed. In the former part, interests are focused on the dynamic phase change of ionic liquid/water mixtures. Some ionic liquids show lower critical solution temperature type phase change after mixing with water. Component ions required for the realization of this type of phase change are proposed related to the water content. In the latter part, dimension control of ionic liquids is summarized considering the marriage of liquid crystals and ionic liquids. Through these results, importance of interface concerning ionic liquids has been mentioned.
