▎ 摘　　要

NOVELTY - The preparation method of hemicellulose-based graphene involves dissolving hemicellulose in deionized water, uniformly mixing, configuring 5-10 %mass aqueous solution of hemicellulose, then adjusting pH value to 9-11 using sodium hydroxide, adding 0.01-1 g/l graphene oxide solution to the mixture and then performing hydrothermal reaction at 120-160 degrees C for 1-24 hours to obtain a graphene solution, washing the graphene solution using ethanol and deionized water and then centrifuging, drying the mixture, and processing. USE - The method is useful for preparation of hemicellulose-based graphene (claimed). ADVANTAGE - The method enables simple and economical preparation of hemicellulose-based graphene with excellent dispersibility and stability in environmentally-friendly manner.
