Hemostatic materials should have efficient and rapid hemostasis, good biocompatibility, nontoxicity. However, common hemostatic sponges often fail due to their weak mechanical strength, low slow hemostasis. Herein, we developed novel multifunctional chitosan/cellulose/tannic acid (CS/OMCC/TA) biocomposite by a freeze-drying method without adding any chemical cross-linking agents. The water absorption rate of the sponge is as high 4404%, blood 5460%. In vitro coagulation tests shown that ability CS/OMCC/TA significantly better than commercial hemostasis materials. DPPH radical scavenging test antibacterial experiments demonstrated excellent antioxidant properties inhibitory effects on Staphylococcus aureus Escherichia coli. Animal showed could rapidly hemostasize within 185 s loss was 107 mg. These findings provide biocompatible for daily emergency trauma treatment surgical
