Polyvinylidene fluoride (PVDF) polymer-based membranes are extensively used in wastewater treatment

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 techniques

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

offering 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.
