▎ 摘　　要

NOVELTY - A graphene oxide loaded zinc-doped copper oxide composite material contains nanoparticles surface having thorn-shaped structure. USE - The graphene oxide loaded zinc-doped copper oxide composite material is useful as disinfectant and antibacterial agent against Escherichia coli and Staphylococcus aureus.(all claimed). ADVANTAGE - The graphene oxide loaded zinc-doped copper oxide composite material has strong rigidity structure and excellent dispersibility, antibacterial ability and efficiency of 99%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene oxide loaded zinc-doped copper oxide composite material, which involves dissolving copper acetate and zinc acetate in double-distilled water, adding copper acetate and zinc acetate to the double-distilled water, then adding graphene oxide and ultrasonically treating to obtain dispersed solution, adjusting the pH value of the solution using aqueous ammonia, adjusting the ultrasonic power for ultrasonically reacting, centrifuging, washing the mixture with double-distilled water and ethanol, and vacuum drying.
