▎ 摘　　要

NOVELTY - Preparation of nano metal-reduction graphene oxide composite material comprises preparing graphene oxide aqueous solution, adjusting the pH value to 8-13, preparing metal salt aqueous solution, adding into the graphene oxide aqueous solution, mixing, adding reducing agent, and subjecting to reduction reaction, where metal is gold, silver, platinum, iron, cobalt, and/or nickel. USE - The method is used for preparing nano metal-reduction graphene oxide composite material as antibacterial material (claimed). ADVANTAGE - The method fully uses the structure characteristic of the graphene oxide molecule and does not need to add additional dispersant. The composite material has excellent bacteriostatic performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the nano metal-reduction graphene oxide composite material.
