摘要/Abstract

日益严重的水资源短缺和水资源污染问题是全球面临的挑战，大力发展海水淡化和水处理技术是缓解该问题的有效途径.近年来，能耗低、环境友好的膜分离技术被广泛用于海水淡化和水处理领域.共价有机框架（Covalent organic framework，COF）膜因其具有大小可控、化学性质可调的孔道，成为潜在的高性能膜分离材料.本综述详细介绍了COF膜合成方法学的研究进展，概述了COF膜在海水淡化和水处理领域的研究，并展望了其在海水淡化和水处理领域的前景和面临的挑战.

The increasing shortage of freshwater resources and water pollution are important challenges facing the world, and vigorous development of seawater desalination and water treatment technologies is an effective way to alleviate this problem. In recent years, low energy consumption and green membrane-separation technology has been widely used in the fields of seawater desalination and water treatment. Covalent organic framework (COF) membranes are potential high-performance membrane separation materials due to their adjustable pore size and chemical environment. In this paper, the research progress of COF-membranes synthesis methodology is introduced in detail, the research of COF membranes in seawater desalination and water treatment is summarized, and the challenges and perspectives of COF membranes for seawater desalination and treatment are elaborated.
Key words: covalent organic framework, seawater desalination, water treatment, membrane separation
