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.
