| Abstract | This work describes the surface grafting of poly (vinylidene fluoride) (PVDF) membrane with poly (ethylene glycol) diacrylate (PEGDA) via low-pressure plasma-induced graft polymerization. The chemical composition and microstructure of the surface modified PEGylated PVDF membranes were characterized by fourier transform infrared spectroscopy (FTIR), X-rayphotoelectron spectroscopy (XPS), scanning lectron microscopy (SEM), atomic force microscopy (AFM) and contact angle measurements. By tuning polymerization conditions, a superhydrophilic and underwater superoleophobic PVDF-g-PEGDA membrane was successfully prepared. Results show that the as-prepared PVDF-g-PEGDA membranes can effectively separate oil-in-water emulsions with high separation efficiency and high fluxes under ultralow pressure. Importantly, the membrane showed excellent mechanical properties, which was also important parameter for practical application. |
