Multifunctional materials with hemostasis, adhesive, and antibacterial properties must be developed to meet the demand for wound hemostasis. In this work, a hybrid hydrogel (ATD-HAp hydrogel) based on a terpolymer and hydroxyapatite (HAp) was prepared by photopolymerization within 1 min under green LED irradiation. The polymer chains of ATD-HAp hydrogel with adjustable tensile and adhesion properties and antibacterial properties were formed by copolymerization of acrylamide, N-[tris(hydroxymethyl)methyl] acrylamide, and dimethyldiallylammonium chloride and methacrylated carboxymethyl chitosan as a cross-linking agent. HAp was added to the hydrogel to release Ca 2+ to promote coagulation. The results showed that ATD-HAp hydrogel had good tensile (196.7 kPa), wet-adhesive (10.3 kPa), self-healing, antibacterial properties, and coagulation. And the ATD-HAp hydrogel had excellent blood compatibility and biocompatibility. Furthermore, the experimental results of the hemostasis model in mice proved that the ATD-HAp hydrogel can significantly shorten the hemostasis time and reduce blood loss. Therefore, the ATD-HAp hydrogel has great potential in the field of wound hemostasis.
