摘　　要：PVDF材料由于其优良的物理化学性质被普遍应用于生活、化工领域,但由于其表面疏水,在使用过程中又易受污染,限制了PVDF材料在水处理方面的应用。本文从PVDF微孔膜亲水改性研究进展出发,对比了不同改性方法的特点并对其进行阐述,主要总结了近年来文献中PVDF膜的亲水改性方法及改性膜的亲水性、水通量和抗污染性能,最后对改性研究进行展望。PVDF material is widely used in the field of life and chemical industry due to its excellent physical and chemical properties. However, due to its hydrophobic surface and susceptibility to pollution in the process of use, the application of PVDF material in water treatment is limited. Based on the research progress of PVDF microporous membrane hydrophilic modification, the characteristics of different modification methods were compared and expounded. The hydrophilic modification methods of PVDF membrane and the hydrophilic, water flux and anti-pollution properties of the modified membrane in recent literatures were summarized. The modification research was prospected.
