共价有机框架(COFs)是一类新兴的高孔隙率结晶有机聚合物,由强的共价键连接而成。COFs材料凭借其优异的物理化学特性(如有序结构、多孔性和稳定性),使其被视为开发尖端分离膜的理想选择。基于COF的膜材料——在海水淡化应用中展现出良好的盐分截留能力。然而,关于其有序结构和分离机制的讨论仍存在争议且缺乏明确证据。因此,系统分析了COFs在膜材料设计中的应用及其在水处理领域的性能表现。同时,着重指出当前COFs材料特性、制备工艺和处理效能等方面存在的技术瓶颈,为未来研究指明方向,以期实现可规模化生产、具有高选择性的工业级分离膜材料。
Covalent organic frameworks (COFs) are a class of emerging high-porosity crystalline organic polymers formed by strong covalent bonds.COF materials,with their excellent physicochemical properties (such as ordered structure,porosity,and stability),are considered an ideal choice for developing advanced separation membranes.COF-based membrane materials have demonstrated good salt rejection capabilities in seawater desalination applications.However,discussions regarding their ordered structure and separation mechanisms remain controversial and lack clear evidence.Therefore,this paper systematically analyzed the application of COFs in membrane material design and their performance in water treatment.Additionally,we highlighted the current technical challenges related to COF material properties,preparation processes,and treatment efficiency,aiming to guide future research toward the development of scalable,industrially viable separation membrane materials with high selectivity.
