▎ 摘  要

The efficient filtering of particulate matter (PM) with particle diameters of less than 0.3 ??m (PM0.3) is challenging. Therefore, mask filter materials with effective interception of PM0.3 and long-term antibacterial performance are urgently required. Herein, polystyrene/fluorinated polyurethane (PS/FPU)-doped graphene oxide???halamine (GO???GH) nanofiber membranes were prepared via electrospinning, and the relevant morphology, structure, and applicable properties were systematically characterized. The diameters of the PS/FPU/GO???GH nanofibers were significantly lower than those of the PS/FPU fibers, and GO???GH doping increased the Young???s modulus and tensile strength of the material by more than 100%. Additionally, in terms of filtration performance, an efficiency of 99.5% was obtained for a nanofiber filter mask constructed using the PS/FPU/GO???GH membrane, with a filtration resistance of 54 Pa. The antibacterial rate of the PS/FPU/GO???GH against Staphylococcus aureus and Escherichia coli reached more than 97%. Furthermore, after 10 chlorination/quenching cycles, a high bacteriostatic rate was still demonstrated for the membrane. This work would provide a strategy for the fabrication of nanofiber filter materials for reusable antibacterial applications. Superscript/Subscript Available
