Abstract: The surface of polypropylene hollow fiber membrane was modified with N,N'-methylene-bis-acrylamide (MBA) by the UV-irradiation, with the benzophenone (BP) as the light initiator. Fourier transform infrared spectrometer (FT-IR) was utilized to characterize copolymer composition. Field emission scanning electron microscopy (FE-SEM) was utilized to observe the fiber surface and section. Results showed that MBA was grafted on the surface of membrane. The influence was researched by changing the concentration of BP, MBA and irradiated time. Results showed that the grafting rate grew rapidly and then declined as the increase the BP concentration. The grafting rate increased at first as the MBA concentration increased, but decreased after the maximum. The grafting rate firstly increased slowly and then increased sharply with the irradiated time extended.
