▎ 摘　　要

NOVELTY - Preparation of graphene oxide/rosmarinic acid composite material comprises dissolving rosmarinic acid in organic solvent, adding 1-2 times its moles condensation activator and 1-3.5 times its moles condensation agent, adjusting pH, reacting for 1-3 hours, adding graphene oxide dispersion liquid, adjusting pH, ultrasonicating for 24-30 hours, centrifuging, and freeze-drying. USE - The method is for preparation of graphene oxide/rosmarinic acid composite material. ADVANTAGE - The method has simple operation, and mild reaction conditions. The composite material has good antibacterial effect.
