▎ 摘　　要

NOVELTY - An antimicrobial membrane (100) comprises a support (120) and a composite coating (110) provided on the support, and has antibacterial effectiveness of 2 or more. The composite coating contains a crosslinked optionally substituted graphene oxide compound. The graphene is crosslinked using a crosslinker chosen from benzoic acid derivative, optionally substituted biphenyl (I), optionally substituted triphenylmethane (II), optionally substituted diphenylamine or optionally substituted 9H-carbazole (IIIA) or (IIIB), and an optionally substituted bis(hydroxymethyl)propanediol (IV). USE - Membrane used for disinfecting microbes (claimed). Uses include but are not limited to air duct of heating system, ventilation system, and air-conditioner, ship hull's, treatment basins, pipes, desalination filters, air filters, hospital equipment and furnishings, counter-tops, and lavatory furnishing. ADVANTAGE - The membrane has excellent antimicrobial effect and selective permeability with respect to water and oxygen. DETAILED DESCRIPTION - An antimicrobial membrane comprises a support and a composite coating provided on the support, and has antibacterial effectiveness of 2 or more. The composite coating contains a crosslinked optionally substituted graphene oxide compound. The graphene is crosslinked using a crosslinker chosen from benzoic acid derivative, optionally substituted biphenyl of formula (I), optionally substituted triphenylmethane of formula (II), optionally substituted diphenylamine or optionally substituted 9H-carbazole of formula (IIIA) or (IIIB), and an optionally substituted bis(hydroxymethyl)propanediol of formula (IV). R1,R2=NH2 or OH; R3,R4=OH, SO3H, SO3Na, or SO3K; R5=H, CH3, or C2H5; R6-R8=H, CH3, -CO2H, -CO2Li, -CO2Na, -CO2K, SO3H, -SO3Li, -SO3Na, or -SO3K; n=0-5; k=0 or 1; m,p=0-10; R9-R12=group chosen from groups of formulae (a1)-(a5); R13=OH, NH2, -CO2H, -CO2Li, -CO2Na, -CO2K, SO3H, -SO3Li, -SO3Na, or -SO3K;and r=0-10. An INDEPENDENT CLAIM is included for method for disinfecting microbes, which involves providing the membrane and exposing the membrane to a working fluid (130) containing microbes. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the antimicrobial membrane. Antimicrobial membrane (100) Composite coating (110) Support (120) Working fluid (130)
