▎ 摘　　要

NOVELTY - Mask based on electro-adsorption effect comprises main body, which includes a first non-woven fabric layer, a first PTFE/graphene composite nanofiber membrane layer, a PTFE nanofiber membrane layer, a second PTFE/graphene composite nanofiber membrane layer, and a second non-woven fabric layer from the outer layer to the inner layer. where the pore diameter of the first non-woven fabric layer and the second non-woven fabric layer is 10-20 mu m, and the thickness is 200-250 mu m. The pore size of the first PTFE/graphene composite nanofiber membrane layer is 5-10 mu m, and the thickness is 9-12 mu m. The pore size of the PTFE nanofiber membrane layer is 3-5 mu m, and the thickness is 9-12 nu m. A power supply part is connected to the mask body, and the anode electrode of the power supply part is connected to the first PTFE/graphene composite nanofiber membrane layer. The cathode electrode of the power supply part is connected to the second PTFE/graphene composite nanofiber membrane layer. USE - Used as mask. ADVANTAGE - The mask is convenient to wear; has relatively simple structure, same thickness as a traditional disposable mask, and anode and cathode layers of the larger pore size PTFE/graphene composite nanofiber membrane and the small pore size PTFE/graphene composite nanofiber membrane are continuously produced by the continuous electric supply to block the dust and germs and the charge will not dissipate with the increase of wearing time.
