Abstract: The present disclosure discloses a method for preparing dual-sensitive cellulose-based aerogel. The DAC (Dialdehyde cellulose), the DAC/PDMAEMA (poly-2-(dimethylamino)ethyl methacrylate) copolymer, the DAC/PDMAEMA/PEI (Polyethylenimine) copolymer are serially prepared, was freeze-dried to obtain a product. The product is the dual-sensitive cellulose-based aerogel, a cumulative adsorption capacity of the dual-sensitive cellulose-based aerogel is 250 mg/g, and a cumulative release amount of the dual-sensitive cellulose-based aerogel in 0.05 mol/L NaH2PO4 (pH=3-8), 0.2% NaCl (pH 8) is 63-90%.

Abstract: A method for preparing anisotropic cellulose-based hydrogel is provided. The method comprises ammoniating the dialdehyde cellulose obtained by oxidizing cellulose using sodium periodate to obtain ammoniated cellulose derivatives; performing Schiff reaction using the ammoniated cellulose derivatives and dopamine to obtain cellulose-based nanosheets; depositing Fe3O4 nanoparticles on a surface of the cellulose-based nanosheets by a deposition method to obtain magnetic cellulose-based nanosheets; and forming the anisotropic cellulose-based hydrogel using the magnetic cellulose-based nanosheets by a polymerization method.
