摘　　要：金属有机骨架(MOFs)材料因其具有孔隙率高、比表面积大和孔道结构易调控等特点已成为近年来国内外研究的热点。将MOFs作为纳米颗粒添加剂引入高分子分离膜中,可使高分子分离膜在特种污水处理时同步获得高通量和高截留率,有望突破传统分离膜渗透性和选择性间相互制约的Trade-off效应。文中综述了常用于高分子分离膜掺杂的不同种类MOFs材料的特性,重点评述了聚合物/MOFs复合膜原位生长法、共混法、界面聚合法等制备方法及其特点,并简述了所得聚合物/MOFs复合膜在重金属离子污水、有机染料、海水淡化等特种分离领域的应用。此外,还指出了聚合物/MOFs复合膜进一步发展可能面临的机遇和挑战。Metal-organic frameworks(MOFs)materials have become a hot topic of research at home and abroad in recent years due to their high porosity,large specific surface area and easily adjustable pore structure.The introduction of MOFs as nanoparticle additives into polymeric separation membranes can enable polymeric separation membranes to obtain high flux and retention rates simultaneously in special wastewater treatment,which is expected to break the Trade-off effect between permeability and selectivity of traditional separation membranes.This paper reviewed the properties of different types of MOFs commonly used for organic membrane doping,focusing on the preparation and characteristics of polymer/MOFs composite membranes by in-situ growth,co-blending and interfacial polymerization,and briefly discussed the applications of the resulting polymer/MOFs composite membranes in special separation fields such as heavy metal ion wastewater,organic dyes,seawater desalination.In addition,possible opportunities and challenges for the further development of polymer/MOFs composite membranes were also pointed out.
