▎ 摘　　要

NOVELTY - Preparing graphene using polysaccharide comprises mixing 0.01-10% polydextrose aqueous solution and 0.01-1 g/l graphene oxide solution, carrying out hydro-thermal reaction at 180-220 degrees C for 1-24 hours to obtain graphene solution, repeatedly cleaning using ethyl alcohol and deionized water, centrifuging, drying and processing to obtain graphene powder. USE - The method is useful for preparing graphene using polysaccharide (claimed). ADVANTAGE - The method is environmentally friendly, does not require stabilizer and dispersant and, and is simple. Graphene is economical, and has good dispersibility and stability.
