Preparation of PVDF hollow fiber membranes supported by PET

PVDF hollow fiber membranes supported by PET which modified by the plasma was prepared. The effects of the treatment time and the power of the plasma,the molecular weight of PVDF,additive concentration on the membrane performance were studied.The results under the experimental conditions showed that the treatment time and the power of the plasma,the molecular weight of PVDF,and additive concentration all showed a considerably effect on the adhesive force of PVDF with PET.The treatment time and the power of the plasma were no evident effect on water flux of PVDF hollow fiber membranes. But the molecular weight of PVDF,and additive concentration all showed a considerably effect on water flux of PVDF hollow fiber membranes.
