Abstract
(EN)
Disclosed are an antibacterial composite nanofiber membrane, a manufacturing method for same, and applications thereof. The antibacterial composite nanofiber membrane comprises a nanofiber membrane and g-C3N4 nanosheets distributed on the surface and in the interior of the nanofiber membrane. At the same time, also disclosed is the manufacturing method for the antibacterial composite nanofiber membrane; also disclosed are the applications of the antibacterial composite nanofiber membrane. Compared with the prior art, the present invention allows the manufacturing of the nanofiber membrane having both antibacterial and filtering functions merely by utilizing a plasma technique and a graphite phase carbon nitride particulate material, and, the material of the membrane has low resistance and high efficiency. At the same time, the manufacturing process of the antibacterial composite nanofiber membrane of the present invention is safe and environmentally friendly, and, the manufacturing method is simple and easy.
