▎ 摘　　要

NOVELTY - Antibacterial material complex comprises modified graphene prepared by reacting with antibacterial reinforcing agent, mixing graphite, sodium nitrate, concentrated sulphuric acid uniformly, adding potassium permanganate and heating and stirring, after stirring, heating and keeping the temperature, then adding de-ionized water, continuously heating and keeping the temperature, adding hydrogen peroxide to stir after finishing the heat preservation, obtaining graphene oxide, dispersing in de-ionized water, dropping chitosan solution and 1-hydroxy benzotriazole, after reacting, filtering and drying the filter cake to obtain pre-modified graphene, dispersing in the acetic acid solution, stirring and adding epoxy chloropropane, adjusting the pH value of reaction liquid, and reacting to obtain the modified graphene. USE - Antibacterial material complex. ADVANTAGE - The antibacterial material complex has multi-layer sterilizing layer, which can effectively destroy the bacterial cell membrane, make the bacterial protein denaturation, block bacterial metabolism, to kill the bacteria, and the sterilizing layer of composite antibacterial material are connected by chemical bond so that the antibacterial component in the composite antibacterial material will not be separated out, volatilizing, falling particulate matter, which greatly increases the service life of composite antibacterial material, at the same time, it does not need to nano-silver the material, which greatly reduces the preparation cost of material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the antibacterial material complex, which involves dispersing the modified graphene in N, N-dimethyl formamide, adding antibacterial reinforcing agent and 4-dimethylamino-pyridine, after reacting, filtering to remove the filtrate, drying the filter cake, soaking the filter cake in sodium hypochlorite solution, adjusting the pH value to soak, filtering and drying to obtain the composite antibacterial material.
