The octa vinyl silsesquioxane (OvPOSS) was used to synthesis POSS grafted ethylene glycol (EG) (EG-POSS). The hydrophilicity and anitifouling property of pure PVDF membrane was improved by incorporating EG-POSS in PVDF membrane.

Hydrophilic Polyvinylidene fluoride (PVDF) flat ultrafiltration membranes were prepared by wet-spinning method. The influence of blending ratio ( the mass ratio of PVDF and PAA), polymer concentration on preparation of blending modified hydrophilic PVDF ultrafiltration membranes were investigated, the technical parameters of preparation of hydrophilic PVDF membranes were determined, and hydrophilic PVDF membranes were prepared. Then, hydrophilic PVDF membranes were characterized in terms of IR spectra, contact angle, scanning electron microscopy images, pure water flux and rejection. The results showed that hydrophilic ultrafiltration membrane could be prepared with PAA and PVDF blends, the hydrophilicity improved greatly, and it was better than traditional PVDF membrane.
