摘　　要：聚醚嵌段聚酰胺共聚物(PEBA)由聚酰胺硬段和聚醚软段所组成,这种软硬结合的结构使其拥有较高的强度和弹性,应用领域广泛。本文介绍了水解开环聚合法和阴离子聚合法等PEBA两种合成方法,以及溶液浇筑法和浸渍涂覆法等PEBA及其复合膜的制备方法。综述了近年来PEBA及其复合膜在诸如有机物/水、污水处理、CO_(2)/N_(2)、烯烃/烷烃等领域的膜分离研究进展,为今后PEBA分离膜的研究应用提供参考。Polyether block polyamide copolymer(PEBA)consists of polyamide hard segments and polyether soft segments,this combination of soft and hard structure makes it has high strength and elasticity,and has a wide range of applications.In this paper,two synthesis methods of PEBA,hydrolysis ring-opening polymerization and anionic polymerization,as well as the preparation methods of PEBA membranes or its composite membranes,such as solution casting and impregnation coating,are introduced.The progress of PEBA membranes or its composite membranes in recent years in the field of membrane separation such as organics/water,wastewater treatment,CO_(2)/N_(2),olefin/alkane,etc.,is reviewed,which pro-vides a reference for the further research of PEBA separation membranes in the future.
