POLYVINYLIDENE FLUORIDE ASYMMETRY-POROUS HOLLOW FIBER MEMBRANE AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a PVDF asymmetric porous hollow fiber membrane and a manufacturing method thereof. More specifically, the present invention relates to a PVDF porous hollow fiber separation membrane which increases the tensile strength by preventing macro-void pores from being formed in a finger-like shape inside the PVDF porous hollow fiber separation membrane; does not block pores on the outer surface of the separation membrane while preventing a rupture of the separation membrane, thereby having a high water permeability at the same time.
