The invention discloses a cationic hydrogel, a preparation method and application thereof, and belongs to the technical field of polymer materials. Cationic hydrogel, prepared from acrylamide, N-(3-dimethylaminopropyl) methacrylamide, N,N-methylenebisacrylamide and a photoinitiator, wherein acrylamide and N-(3 - The molar ratio of dimethylaminopropyl) methacrylamide is (77-87): (10-20). The cationic hydrogel of the present invention can effectively adsorb negatively charged substances through the electrostatic action of N-(3-dimethylaminopropyl)methacrylamide cations. The wound dressing prepared by the cationic hydrogel of the present invention can effectively absorb the free nucleic acid at the wound infected with diabetes, and can effectively inhibit the inflammatory response at the wound, thereby accelerating wound healing. |
