Fluorine-containing Ionic Liquids and Functional Materials

Introduction of fluorine stimulated the rapid development of ionic liquids. Fluorine containing ionic liquids have unique properties, such as lower melting point and viscosity, hydrolytically stability and environmen-tally benign nature. As the main varieties of ionic liquids, fluorine containing ionic liquids progressed from water stability to functional system. They show magnitude potential power and wider application perspective in the process of industrialization course of green chemical engineering, with the advantages of designable and green character. This article is intended to briefly summarize the classification, physical and chemical properties of fluorine - contai-ning ionic liquids. The emphasis is put on research and application status of perfluoroalkyl - ionic liquids, function- al fluorine-containing ionic liquids, membrane modification by ionic liquids and polymeric fluorine-containing i-onic liquids.
