摘要
Covalent organic frameworks (COFs) are porous nanomaterials that consist of organic structural units connected by covalent bonds. Due to the advantages of large specific surface areas, high porosity, ordered structure and high stability, COFs are considered as ideal materials for fabricating high-performance separation membranes, which receives wide attention in nanofiltration membrane studies. This review briefly introduces the research progress of COFs nanofiltration membranes fabricated by blending, layer-by-layer assembly, interfacial polymerization and in-situ growth in recent year. The characteristics of different preparation methods are analyzed. Finally, the existing problems in COFs nanofiltration membranes are discussed and the future development is prospected. © 2021, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
