| Abstract: | A poly(vinylidene fluoride)-graft-poly(N-isopropylacrylamide)(PVDF-g-PNIPAAm) copolymer was synthesized,and from which a novel temperature-sensitive copolymer hollow fiber membrane was prepared based on the technique of dry-wet spinning.The structures of the hollow fiber membrane were characterized by Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),differential scanning calorimetry(DSC),scanning electron microscope(SEM),respectively.The results showed that the PVDF-g-PNIPAAm hollow fib... |
