Graphene antibacterial film and air-exhaust-free cube vacuum compression bag

[0025] The invention provides a graphene antibacterial film, wherein the main materials used include by weight: 45 parts of graphene oxide, 25 parts of polyurethane resin, 15 parts of polyethersulfone resin, 10 parts of polytetrafluoroethylene resin, 8 parts of polyethylene resin, 50 parts of organic solvent, 5 parts of mugwort extract, 2 parts of sodium carboxymethyl cellulose, 1 part of tea polyphenol and 3 parts of cationic nano-silver antibacterial agent;

[0026] The preparation method of graphene antibacterial film is as follows:

[0027] Step 1: Using graphene oxide as a raw material, using a strong oxidant, under the action of stirring, chemically intercalate graphite, shear peeling, dispersing and refining, and sieve to obtain graphite oxide powder, and prepare cationic nano-silver The antibacterial agent and graphene oxide powder are fully mixed evenly and set aside;

[0028] Step 2: Add the mugwort extract into the organic solvent and stir evenly to obtain an organ...
