To address the limitations of current skin wound dressings in antibacterial activity,drug release,and biocompatibility,a dual-network composite hydrogel based on graphene oxide (GO) and syringic acid triethanolamine salt (STA),named GO@STA/HPS/SA,was developed to promote healing of infected wounds.The material was characterized by UV spectrophotometry,FTIR,and SEM.Its swelling rate,antibacterial properties,in vitro release,cytocompatibility,and efficacy in a mouse skin defect model were evaluated.Results indicated that STA significantly inhibited E.coli and S.aureus.At pH 6.0 and 32℃,the hydrogel exhibited favorable STA release.The GO@STA/HPS/SA group showed superior biocompatibility and promoted cell proliferation,with significantly enhanced wound healing compared to controls.The GO@STA/HPS/SA dual-network hydrogel demonstrates excellent antibacterial activity,controlled drug release,and biocompatibility,significantly accelerating infected wound healing.
