摘要：

碳分子筛膜（CMS）作为新型无机多孔膜，其高渗透系数、高选择性的优势使其具有代替传统气体膜分离材料的广阔前景。深刻认知CMS膜的形成机理；阐明前驱体结构与CMS的微观结构与分离性能的关联机制能够实现CMS膜的微观结构调控、气体分离性能优化的目标。本文系统总结了近十年来CMS膜的制备工艺、新型CMS膜前驱体的选择思路及设计制备现状，重点介绍了基于聚酰亚胺、自具微孔聚合物的CMS膜的制备；探讨了实现CMS膜性能优化的主要调控手段，着重介绍了前驱体交联改性对CMS膜结构与性能的调控；通过分析CMS膜实现放大生产的制约因素，总结了CMS膜规模化制备的研究进展；并提出了可行的CMS膜结构调控手段，并对未来可工业化CMS膜的研究和制备提出合理展望。

As one new type of inorganic porous membranes, carbon molecular sieve membrane with its advantages of high permeability and selectivity holds great potential to replace the conventional gas separation membranes. Fundamental understanding of the formation mechanism of CMS membranes and clarifying the correlation between precursor performance and CMS microstructure and separation performance can achieve the goal of microstructure control and optimization of gas separation performance. This paper systematically summarizes research progress on preparation process of CMS membrane in the past ten years, various precursors based CMS developments and the current situation of design and preparation. The preparation of CMS membranes based on polyimide and Polymer of Intrinsic Microporous was specifically discussed. Research work on tailoring CMS membrane microstructure and performance optimization was also discussed with the focus on precursor cross-linking modification. The research progress of large-scale CMS membrane preparation is summarized. The feasible CMS membrane structure control methods are proposed, and future developments of large-scale CMS membranes preparation are proposed.
