Preparation of PVDF-g-PSBA Membrane by Homogeneous Solution Gamma-Ray Co-Irradiation and Its Antibacterial Effects
Abstract
Poly(S-bioallethrin) (PSBA) was grafted onto the polyvinylidene fluoride (PVDF) molecular chain through a gamma-ray irradiation method to prepare the PVDF-g-PSBA membrane. Fourier transform infrared spectroscopy (FTIR) of different membranes confirmed the effective progress of the grafting reaction. The microstructure of the membrane before and after irradiation was analyzed by scanning electron microscope (SEM), illustrating that gamma-ray irradiation did not cause damage to the membrane structure. The original PVDF membrane and the modified PVDF-g-PSBA membrane were immersed in an Escherichia coli culture medium, and the antibacterial effects of membranes were tested, confirming the positive effect of the PVDF-g-PSBA membrane on inhibiting bacterial growth. This research could have market application value in terms of altering membrane materials and enhancing membrane performance.
