Abstract:

Ionic liquids can be readily modified structurally to have desired chemical and physical properties by the incorporation of specific functional groups. Functionalized ionic liquid can be used in separation，electrochemistry，catalysis，organic synthesis and other fields，and has become a hot research subject in the ionic liquid area. In this paper，research progress of functionalized ionic liquid with fluoroalkyl，amine and other polar groups for CO₂ absorption is summarized，and the CO₂ separation performance of supported functionalized ionic liquid membranes is also introduced. The problems to be resolved in the future researches are presented.
