NOVELTY - Preparing graphene physical antibacterial hydrogel dressing comprises (1) preparing graphene oxide dispersion liquid, dispersing the graphite oxide prepared by the Staudenmaier method in purified water, adding aqueous ammonia, and adding 95% ethanol, (2) preparing the hydrogel, adding NP-700, CMC and PVPP to the glycerol in batches, mixing and stirring, and then stirring under vacuum to obtain the hydrogel, and (3) adding the graphene oxide dispersion to the hydrogel and stirring to obtain a graphene physical antibacterial hydrogel dressing. USE - The hydrogel dressing is useful to reducing heat in the human body for reducing the temperature. ADVANTAGE - The hydrogel dressing has high water content.
