Superhydrophilic and underwater superoleophobic PVDF membranes via plasma-induced surface PEGDA for effective separation of oil-in-water emulsions

- The surface grafting of poly (vinylidene fluoride) (PVDF) membrane with poly (ethylene glycol) diacrylate (PEGDA) was obtained via low-pressure plasma-induced graft polymerization.
- The PVDF-g-PEGDA membranes became superhydrophilic and underwater superoleophobic, and showed also excellent mechanical properties.
- The as-prepared PVDF-g-PEGDA membranes can effectively separate oil-in-water emulsions.
