| description | The invention discloses a preparation method of a magnetic graphene cellulose composite material and application of the magnetic graphene cellulose composite material in a flexible luminescent device. The preparation method comprises the following steps: preparing Fe3O4 nano-particles, aminating the Fe3O4 nano-particles, and preparing a covalent cross-linking magnetic graphene cellulose composite material; adding covalent cross-linking magnetic graphene oxide into water to prepare a covalent cross-linking magnetic graphene oxide dispersion liquid; fe3O4 in the magnetic graphene oxide prepared by a covalent cross-linking method is wrapped by the graphene oxide; cellulose filter paper is placed in a covalent cross-linking method magnetic graphene oxide solution, and dipping, drying and reduction are carried out under the regulation and control of a magnetic field. The magnetic graphene cellulose composite material has good conductivity through magnetic field regulation and control. The composite material is use |
