| titleOfInvention | Medical dressing compounded by chitosan and polypropylene carbonate and preparation method thereof |
| abstract | The invention discloses a medical dressing compounded by chitosan and polypropylene carbonate and a preparation method thereof. The invention adopts the polypropylene carbonate as the dressing basement membrane, which is beneficial to reducing the discharge amount of medical solid garbage and reducing the application of petrochemical products; the air permeability of the poly (propylene carbonate) film is improved by making holes by using a hole making agent; the chitosan serving as a hydrophilic degradable biological material is grafted on the hydrophobic polypropylene carbonate by using the polydopamine as a bionic biological adhesive, and is modified by the polydopamine and the chitosan, so that the physical property and the biological property of the polydopamine serving as a dressing are improved; and spermidine is used as a cross-linking agent, so that chitosan is better fixed on the surface of PPC through secondary cross-linking, and bioactive small molecular spermidine is introduced to improve the rejection inflammatory reaction of the wound surface, help to shorten the wound surface repair time and reduce scar formation. |
