The hydrophilic modification of polyvinylidene fluoride (HP-PVDF) membranes has attracted more and more attention in recent years for oil / water separation. However, there are still challenges in easily manufacturing an inexpensive, environmentally friendly, and durable HP-PVDF membrane. In this study, a new type of HP-PVDF membrane made of cellulose-TA-PVA-PVDF with excellent micro-nano-porosity, favorable durability, superhydrophilicity and underwater superoleophobia due to strongly adhering regenerated cellulose (RC) on PVDF membrane with supramolecular adhesive made: complex of tannic acid and polyvinyl alcohol (TA-PVA). The manufacturing method had merits of simple, light weight, non-toxic and inexpensive. The pore size of the RC layer on the surface of cellulose-TA-PVA-PVDF was conducive to demulsification, and the highly adhesive TA-PVA complex was helpful in improving the durability of the cellulose-TA-PVA-PVDF membrane. The developed cellulose-TA-PVA-PVDF membrane not only showed an excellent oil / water separation efficiency (99.99%) and a promising flow (318 L / m2⋅h⋅bar), but also achieved a separation efficiency of 99, 7% after 30 cycles and 30 minutes of ultrasound. More importantly, Cellulose-TA-PVA-PVDF showed excellent separation performance for real oil-seawater mixtures. Thus, the cellulose-TA-PVA-PVDF membrane had considerable potential for practical applications in oil / water separation.
