This study examines Poly vinylidene fluorine (PVDF) membrane modification by glycidyl methacrylate (GMA) using the radiation induced graft polymerization. To evaluate the effects of GMA monomer concentrations and absorbed doses, various experimental conditions were tested in the laboratory. The morphology of membrane surface was significantly changed by increasing radiation intensity and GMA concentration. The roughness of membrane surface was decreased from 480 nm to 210 nm. The sulfonyl group and elemental sulfur on the membrane surface were analyzed using FT-IR and EDS. The concentration of elemental sulfur was increased as degree of grafting was increased. The water flux of grafted membrane showed 10 times higher than that of virgin membrane. Additionally, the grafted membrane shows good flux recovery in wastewater filtration. This result leads to the PVDF membrane was effectively functionalized by radiation-induced grafting polymerization.
