This invention belongs to the field of biomedical materials technology, specifically relating to a chitosan hemostatic sponge and its preparation method. This patent addresses the problems of residual acetic acid and side reactions, low strength, and low absorbency caused by cross-linking methods during the preparation of chitosan hemostatic sponges. It innovatively proposes a method for physically cross-linking chitosan hemostatic sponges using hydrogen bonding-electrostatic synergistic superabsorbency based on alcohol-regulated substances. By introducing alcohols to regulate the electrostatic interaction between chitosan amino groups and acetic acid, while simultaneously adjusting the hydrogen bonding interaction between chitosan molecules, and introducing other polymer materials to construct a semi-interpenetrating network, the overall material properties are enhanced. The chitosan hemostatic material prepared by this process, although without the addition of cross-linking agents, still exhibits an insoluble sponge-like structure, good flexibility, and excellent absorbency and hemostatic effect.
