摘　　要：由于聚偏氟乙烯(PVDF)具有优异的力学性能和化学性能所以经常用作水处理膜材料,但PVDF膜表面能低,本身疏水性较强,从而导致膜易被污染、堵塞使得膜水通量降低。因此,对PVDF膜亲水改性尤为重要。综述了不同系列的亲水性金属有机骨架(MOFs)复合材料对PVDF膜亲水改性的最新研究进展。Polyvinylidene fluoride(PVDF) is often used as water treatment membrane because of its excellent mechanical and chemical properties, however the surface energy of PVDF membrane is low and its hydrophobicity is strong, which leads to the membrane being easily polluted and blocked, reducing the membrane water flux. So it is particularly important for PVDF membrane hydrophilic modification. The latest research progress of hydrophilic metal organic framework(MOFs) composites on hydrophilic modification of PVDF membrane was reviewed.
