WOUND COVERING AND PREPARATION METHOD THEREOF
The present invention relates to a wound covering with prominent biocompatible and accelerated wound-healing and its preparation method thereof. The wound covering comprises a film prepared from collagen and Dopa-containing protein—mussel adhesive protein, which is immobilized on collagen by chemical cross-linking, thus enhances the stability of protein structure and maintains the activity of collagen and mussel adhesive protein. The wound covering has excellent mechanical strength and can be trimmed into any shape; it accelerates tissue epithelisation and promotes wound healing with good biocompatibility, non-adhesive to the wound and no further wound damages.
