离子液体支撑液膜在较大跨膜压差（0.25～0.3MPa）下的稳定性较差，具有较好稳定性的聚离子液体膜和离子液体-聚合物共混膜等逐渐被关注。本文综述了离子液体支撑液膜、聚离子液体膜、离子液体?聚合物共混膜等离子液体膜CO2分离性能、分离机理及稳定性的最新研究进展，介绍了无机颗粒-离子液体-聚合物共混膜的研究现状。指出离子液体膜的高 CO2渗透通量与高稳定性之间的矛盾、共混膜结构调控难等问题是其工业化应用的主要障碍，提出开发新的膜材料、改进制膜工艺以减小膜厚、优化膜结构是提高膜的 CO2渗透和分离性能，并保持膜稳定性的有效途径。无机颗粒-离子液体-聚合物共混膜兼有较高的CO2分离性能和较好稳定性，具有良好的应用前景，对其制备方法、结构、性能及CO2分离机理的研究将成为这一领域的热点。

Supported ionic liquid membrane (SILM) has relatively low stability at high cross-membrane pressure difference (0.25-0.3MPa). Polymerized ionic liquid membrane and ionic liquid ? polymer mixed membrane can eliminate the instability problem of the SILM. This review presented a summary on the latest developments in the research of SILM,polymerized ionic liquid membrane and ionic liquid ? polymer mixed membrane used for CO2 separation with respect to the separation performance,transport mechanism and stability. The research on a three-component mixed-matrix membrane,inorganic particle?ionic liquid?polymer mixed membrane,by dispersing inorganic nano-particles in polymer matrix containing ionic liquid was also introduced. It was indicated that the challenges for the ionic liquid membranes technologies applied on an industrial scale include the trade-off between high CO2 permeation rate and high stability,and the difficulties with the structural arrangement of the mixed membrane. Significant improvements of the separation performance and stability of the ionic liquid membranes can be achieved by developing new membrane materials,improving membrane fabrication techniques to reduce membrane thickness and optimize membrane structure. Inorganic particle ? ionic liquid ? polymer mixed membrane showed a good prospect in CO2 separation for its higher separation performance combining with better stability. The study on the fabrication,structure,separation performance and mechanism of the new type of membrane will inevitably draw considerable attention.
