Abstract: In this paper, the PVDF-g-PNIPAAm/PVDF blend hollow fiber membrane was prepared with dry-wet spnning technique. Influence of take-up speed on structures was studied. The results indicated that the sponge-like structure becomes gradually thin and wall thickness reduced with the increase in take-up speed. The rough surface structures were formed on both the inner and outer surfaces of fiber membranes fabricated with a higher PVDF-g-PNIPAAm take-up speed.
