Abstract | The invention discloses a composite aerogel dressing and a preparation method thereof. The composite aerogel dressing is prepared from the following raw materials in percentage by mass: 4 to 10 percent of polyvinyl alcohol, 5 to 50 percent of water-soluble chitosan, 0.1 to 3 percent of graphene oxide and the balance deionized water. The preparation method of the composite aerogel dressing comprises the following steps of: preparing a mixed solution according to the mass percentage, freezing the mixed solution, then unfreezing for multiple times to obtain hydrogel, and freeze-drying the obtained hydrogel to obtain the composite aerogel dressing. The composite aerogel dressing has the functions of stopping bleeding, resisting bacteria and promoting wound healing, is low in cost, environmentally friendly and simple in preparation process, has no special requirement on equipment and relatively good biocompatibility, and has great potential in the aspect of medical wound dressings.
