PVDF is one of most commonly used materials in filtration and pervaporation membrane manufacturing processes due to its excellent thermal stability and chemical resistance. As, however, it has hydrophobic characteristics, some obstacles still need to be overcome. So, it is necessary to improve the hydrophilicity of membrane. In this study, membranes constituted with neat PVDF and PVDF blended with different weight percentages of partially sulfonated poly(phenylene sulfide) [sPPS] were prepared by NIPS process and compared with each other. The results of pure water flux, antifouling and retention efficiency of blood serum albumin, the flux and solute rejection or selectivity of different feed solutions using PEO illustrated that the addition of hydrophilic sPPS obviously affected the structure and performance of the PVDF/sPPS membranes, resulting in better filtration performance.
