Polyvinylidene fluoride(PVDF)polymer-based membranes are extensively used in wastewater treat-ment,yet their partially hydrophobic nature poses significant challenges.Numerous studies have focused on creating super-wetting membranes to enhance the water affinity of PVDF membranes.This review provides a comprehensive discussion on the hydrophilization of PVDF-based membranes,examining the chemical and physical properties that influence water affinity.Followed by various fabrication tech-niques,appropriate modifier materials,efficient operational conditions,and recent advancements in hydrophilization methods.Additionally,the review systematically evaluates the performance of these hydrophilized membranes in separating surfactant-stabilized oil-in-water emulsions,highlighting the importance of long-term stability and environmental considerations.The antifouling mechanisms and the effectiveness of hydrophilic membranes in oil-water separation processes are also discussed,of-fering insights into the development and application of these technologies.The discussion explain in this review provides important information for the research of wastewater treatment,green material and green industry.
