▎ 摘　　要

NOVELTY - The film has a substrate coated with graphene oxide. Antibacterial agent and macromolecule polymer are dissolved using a solvent, where antibacterial agent and macromolecule polymer are coated on the substrate. The antibacterial agent is at least one of biguanides disinfectant and quaternary ammonium salt disinfectant. The high molecular polymer is at least one of polymethyl acrylic acid, polyamide, polyethylene imine, polyethylene glycol, and chitosan. The substrate is any one of nonwoven fabric, polyacrylonitrile, polyvinylidene fluoride, nylon, and polycarbonate. The solvent is at least one of water, methanol, ethanol, and dimethyl sulfoxide. USE - Graphene oxide air sterilizing film for use in an air purification field. ADVANTAGE - The graphene oxide air sterilizing film is convenient and effective to sterilize and purify the air, and has good sterilizing effect, and intercepts dust under the condition of not affecting the air flow. The method is simple and easy for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene oxide air sterilizing film preparation method.
