Introduction Polyvinylidene fluoride (PVDF) has been widely used as one of the membrane materials, well-known for its excellent chemical resistance and thermal stability.
The hydrophobic faces of membranes can become more hydrophilic through mixing the hydrophilic polymers or inorganic materials in PVDF dope solutions, grafting hydrophilic branches and depositing hydrophilic film on the base hydrophobic membranes, as reported by Ochoa et al. [13].
Domestic scientists have done a lot of researches about modification of PVDF membrane [14-18], which indicates that Graft Modification and blending of membrane materials are the main direction of future development of hydrophilic membrane.
