▎ 摘　　要

NOVELTY - Preparing functionalized graphene, comprises preparing an alkaline organic solution, respectively taking graphene and aldehyde addition reactants at a mass ratio of 1:10-30, and adding into alkaline organic solution, stirring the mixed solution and reacting at 25-80℃ for 0.5-10 hours, and allowing to stand for cooling, filtering the reaction solution, washing and drying to obtain functionalized graphene. USE - The method is useful for preparing functionalized graphene. ADVANTAGE - The method optimizes the graphite preparation method to improve the dispersion performance of graphite, to improve dispersion stability of the graphene in the solvent, and to provide modified graphene with hydrophobic and oleophylic properties. The whole production process is green and environment-friendly, and the cost is low. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a functionalized graphene.
