Abstract
AbstractIn the present study, the temperature sensitive PVDF‐g‐NIPAAm HFM was prepared by grafting N‐isopropylacrylamide (NIPAAm) on poly(vinylidene fluoride) (PVDF) hollow fiber membrane (HFM) using a novel approach, alkaline treatment method. The structures of PVDF‐g‐NIPAAm HFM were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), respectively. The effects of alkaline treatment time and grafting yield on the mechanical properties of PVDF HFM were measured and analyzed. In addition, the temperature sensitive behavior of PVDF‐g‐NIPAAm HFM and the effect of grafting yield on the temperature sensitive behavior were investigated by the flux of pure water and the rejection of ovalbumin. © 2006 Wiley Periodicals, Inc.
