摘　　要：聚偏氟乙烯(PVDF)多孔膜虽因其优异性质已用于社会生产的多个领域,但其性能仍不能满足人们要求,因此,PVDF多孔膜的制备和改性一直是人们关注的焦点。总结了PVDF多孔膜的制备和改性研究的主要进展,重点从溶剂的选择、浸渍沉淀法、热致相转换法、表面改性和共混改性等方面进行了阐述,并指出PVDF多孔膜的亲水性和强度等方面仍将是今后一段时期内的研究重点,此外,PVDF多孔膜与催化剂相结合的催化膜也将成为水处理领域的新兴研究热点之一。Poly（ vinylidene uoride） （PVDF）membrane has been applied in many fields because of its excellent properties,but its performances should be improved further, the preparation and modification of PVDF mem- brane has been focusing all the time. This article summarized the developments of preparation and modification of porous PVDF membrane. The method of preparation such as the selection of solvents, the progress of immersion precipitation, the progress of thermally induced phase separation, and the methods of surface and blending modification are illustrated. The hydrophilicity and strength of PVDF should be studied further. In addition, the catalytic PVDF membrane should be pay attention to in the field of water treatment.
