Abstract:

Porous membranes were prepared using the phase inversion method from poly(vinylidene fluoride)-graftpoly( N-vinyl pyrrolidone) (PVDF-g-PVP) powders, which were synthesized via -ray induced graft polymerization (pre-irradiation). Chemical compositions, thermal behavior, morphology and hydrophilicity of the membranes were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, element analysis, thermalgravimetric analysis, differential scanning calorimetry, scanning electron microscopy and contact angle measurements, respectively. Permeation experiments were conducted to evaluate the water flux, and the dynamic BSA fouling resistance performances were investigated, too. All the experimental results indicate that the PVDF-g-PVP membranes demonstrate better separation performances over the pristine PVDF membrane.
