Abstract：
Polyvinylidene fluoride (PVDF) microporous membranes are widely used in water treatment due to their excellent chemical stability and mechanical properties. However, their strong hydrophobicity can lead to porous membrane fouling, significantly reducing separation efficiency and increasing operating costs. Based on the Web of Science database, this paper analyzes the literature of the past 20 years and focuses on reviewing the research progress of hydrophilization modification of PVDF porous membranes from 2020 to 2025. The review covers three aspects: surface modification, bulk modification  and combined methods. It compares the effects of different modification strategies on water contact angle, flux recovery rate and anti-fouling performance, and analyzes the advantages and disadvantages of various modification methods. Finally, it is pointed out that future research should focus on green and low-cost composite modification technologies and deepen the mechanism research to expand the application potential of PVDF porous membranes in the treatment of complex wastewater.
