The invention discloses a preparation method of medical antibacterial gauze, comprising the following steps: (1) modifying hydroxypropyl-β-cyclodextrin: arranging the gauze on a finishing comprising hydroxypropyl-β-cyclodextrin and citric acid Padding treatment in liquid, then steam crosslinking, and washing with water to obtain hydroxypropyl-β-cyclodextrin-modified gauze; (2) Modified graphene: dipping the hydroxypropyl-β-cyclodextrin-modified gauze In the graphene oxide dispersion liquid, add ascorbic acid, heat for reaction, take out and wash with water to obtain graphene-modified gauze; (3) Inclusion of thrombin: Immerse the graphene-modified gauze in thrombin solution for vibration reaction; after taking out The medical antibacterial gauze is obtained by washing with water and drying with cold air. In the invention, the cyclodextrin containing thrombin is used to anchor the graphene on the surface of the gauze, so as to prepare the medical gauze with good antibacterial and hemostatic functions. |
