This invention discloses a gellizable, dynamically adhesive, moist wound healing dressing and its preparation method and application. The dressing is constructed from water-soluble cellulose derivatives, chitosan derivatives, and silk fibroin through physical cross-linking and freeze-induced phase separation, achieving dry-state stability without the need for chemical cross-linking agents. Upon contact with wound exudate, a gel layer forms.
