The invention discloses a double network aerogel, a preparation method and application thereof, and belongs to the technical field of material preparation. Specifically disclosed is a preparation method: immersing wood in a mixed solution of glacial acetic acid and hydrogen peroxide to prepare anisotropic cellulose-based aerogel; using acrylamide as a monomer, N-N' methylenebisacrylamide As a cross-linking agent, ammonium persulfate is used as an initiator to prepare a hydrogel solution; then the prepared cellulose-based aerogel is placed in the hydrogel solution for heating reaction, and freeze-dried to obtain a double network aerogel. The preparation process of the invention is simple, the raw material sources are wide and the cost is low, and a new material is provided for the decolorization treatment of dye wastewater. |
