Wound　dressing　is　a　kind　of　significant　artificial　materials　for　protecting　injured　tissues　and　promoting　wound　healing.　However,　fabrication　of　antibacterial　wound　dressing　usually　involves　tedious　procedures　and　toxic　components.　Herein,　we　demonstrate　a　multifunctional　chitosan/silver/tannic　acid　(CS/Ag/TA)　cryogel　based　on　an　economic　method　to　block　acute　hemorrhage　and　promote　wound　healing.　The　prepared　CS/Ag/TA　cryogel　not　only　performs　steady　stability　and　compressibility,　but　also　shows　good　antibacterial　ability　for　both　S.　aureus　and　E.　coli.　Attributing　to　TA　molecules,　the　CS/Ag/TA　cryogel　can　effectively　scavenge　more　than　95%　of　free　radicals,　showing　effective　oxidation　resistance.　Due　to　the　porous　structure　and　positive　charge　of　CS,　the　prepared　cryogel　exhibits　good　hemostatic　capability　with　a　hemostasis　time　less　than　20　s.　Benefitting　from　the　good　biocompatibility　and　cell　proliferation,　the　CS/Ag/TA　cryogel　can　significantly　promote　wound　repair　in　the　skin　incision　model.　All　the　results　indicated　that　the　greenly　fabricated　cryogel　can　be　widely　applied　in　clinic　for　hemostasis　and　wound　healing.
