A Graphene Oxide–Based Hydrogel with Excellent Adhesive, Tough, and Antibacterial Properties

Abstract Hydrogels have attracted extensive attention in the field of wound dressing because of the high water content and a structural similarity to human soft tissue. However, the hydrogels are usually vulnerable and easy to be destroyed during movement. Moreover, the hydrogels without antibacterial function cannot prevent bacterial infection during chronic wound healing. In this work, graphene oxide (GO) containing polyacrylamide hydrogel with both adhesiveness and superior mechanical properties was prepared. Since GO possesses good photothermal conversion capability and photodynamic property, the hybrid hydrogel exhibits excellent antibacterial property under the irradiation of near-infrared light.
