含氟离子液体与分离膜材料

Fluorine-containing ionic liquids and separation membrane materials

氟元素赋予了离子液体更低的熔点和粘度、更好的耐水性和环境友好性。简要总结了含氟离子液体及其用于聚离子液体膜、支撑液膜和离子交换膜等分离膜材料方面的研究进展,并对其应用前景进行了展望。

Fluorine-containing ionic liquids are endowed with unique properties, such as lower melting point and vis- cosity, hydrolytical stability and environmental benign nature. The research progress of fluorine-containing ionic liquids and their applications in polymeric membrane of ionic liquids, supported membrane and ion-exchange membrane was summa- rized. The application prospects of fluorine-containing ionic liquids were discussed.
