摘要：

共价有机骨架（COFs）材料是一类新型的有机聚合物，由有机分子单体通过共价键聚合而成。COFs具有高孔隙率、高比表面积、孔结构可调等优点，是分离膜材料的理想选择。与传统的聚合物分离膜相比，COF膜具有密度低，通量高，选择性高等优势，近年来已经成为膜领域的研究热点。目前，COF膜的研究和应用正处于快速发展阶段，相关的研究主要集中于COF膜材料的设计和制备，其在膜分离领域应用的最新进展尚缺乏系统梳理。本文结合国内外众多学者的研究成果，总结了COF膜在气体分离、液体分离领域的最新应用进展，对COF膜的发展提出建议和展望，为未来COF膜在膜分离领域的发展和实际应用提供借鉴。

Covalent organic frameworks (COFs) as a new class of organic polymers, consist of organic molecular monomers polymerized by covalent bonding. With the advantages of high porosity, high specific surface area and adjustable pores, COFs are ideal as separation membrane materials. Compared with traditional polymeric separation membranes, COF membranes have the advantages of low density, high flux and tunable structure, and have attracted large attention in the membrane field in recent years. At present, the research and application of COF membranes are in a rapid development stage, and the research mainly focuses on the design and preparation of COF membrane materials, but the latest progress of application in membrane separation field is not yet systematically sorted out. In this work, we summarize the latest progress of COF membranes in gas separation and liquid separation, and provide an outlook on the future development of COF membranes for the future development and practical application in membrane separation field.
