High-strength anti-bacterial composite cryogel for lethal noncompressible hemorrhage hemostasis: Synergistic physical hemostasis and chemical hemostasis

• A series of double-network cryogels were prepared. • The mechanical strength of the double-network cryogels is high. • The cryogels shows excellent hemostasis in vivo. • The cryogels can effectively deal with non-compressible bleeding.
