▎ 摘  要

NOVELTY - Preparing oriented graphene oxide-reinforced cellulose-based material involves dissolving the microcrystalline cellulose in the dimethylacetamide solvent of anhydrous lithium chloride to obtain a cellulose solution. The water in the aqueous graphene oxide solution is replaced with dimethylacetamide by rotary evaporation to obtain a graphene oxide solution. The cellulose solution obtained is mixed and the graphene oxide solution obtained, and stirred for 30-35 minutes to obtain a mixed solution. The mixed solution is poured into the mold and stand for 7-9 days in an open space, taken out and placed in water for replacement, changed the water once a day and wait for dimethylacetamide in the gel after the lithium chloride is completely replaced with water, and subjected to directional freezing and then freeze-dried to obtain final product. USE - Method for preparing oriented graphene oxide-reinforced cellulose-based material. ADVANTAGE - The method enables to prepare oriented graphene oxide-reinforced cellulose-based material improves the anti-compression strength of the material.
