▎ 摘　　要

NOVELTY - Preparation of functionalized graphene oxide involves adding graphene oxide, haloammonium salt and catalyst to organic solvent for esterification, stirring at 50-100 degrees C, centrifuging fully reacted mixture, removing supernatant, washing lower liquid with water and ethanol, freeze-drying collected solid to obtain product (A), mixing (A) and sodium hypochlorite according to 1:2-100 mass ratio, reacting completely at 25-50 degrees C, washing product with water and freeze-drying washed product. The oxygen content in graphene oxide is 20-50% and total oxygen content in carboxy group is 15%. USE - Preparation of functionalized graphene oxide (claimed). ADVANTAGE - The method prepares functionalized graphene oxide with excellent antibacterial properties.
