摘　　要：The COVID-19 pandemic has underscored the significance of antibacterial protective materials.Utilizing high-performance antibacterial masks proves to be effective in preventing the spread of respiratory diseases.Herein,we demonstrate a self-cleaning antibacterial mask constructed from the fiber@ZnO composite membrane,utilizing the strong interfacial adhesion of polydopamine(PDA).With a ZnO NPs immersion solution concentration of 1.0 mg/mL,the ZnO NP content in fiber@ZnO reaches 6.5%.The fiber@ZnO demonstrates bactericidal rates exceeding 99%against Gram-positive(S.aureus)and Gram-negative(E.coli)bacteria,and exhibits an inhibition rate exceeding 99.99%against the H1N1 influenza virus.The hydrogen bonding and electrostatic interaction between ZnO nanoparticles(NPs)and PDA can keep a stable combination of NPs and fiber.Antibacterial masks constructed by the fiber@ZnO composite membrane exhibit superior self-cleaning performance and effectively eliminate pathogenic bacteria in aerosols compared with commercial N95 masks.The mussel-bionic strategy presents a viable approach for developing novel antibacterial fibers,with significant application potential in reducing the risk of human infection and preventing the re-transmission of pathogens.
