The present application discloses a virus trapping material and a production process, including a support material layer, a coating layer and a graft modification layer. The support material layer is a medical non-woven air filter material; the outer layer of the support material is coated with a thickness of A coating layer not greater than 50 nm; the grafted modification layer is coated on the side of the coating layer away from the support material layer, and the thickness of the grafted modification layer is not greater than 10 nm; the coating layer comprises by weight, 1,000 parts of gelatin, 0.5-3 parts of Cu/Cu 2+ , 40-200 parts of cellulose, and 50-800 parts of glycyrrhizic acid; the graft modified layer is in parts by weight, 1 part of fibronectin, and 0.05-3 parts of RNaseA enzyme; The branch-modified layer is used for specific affinity adsorption and capture of virus particles passing through the vicinity of the micropores and then cooperates with the coating layer to inactivate the virus. The material can effectively capture viruses, and combined with copper ions can simultaneously inactivate viruses. |
