▎ 摘　　要

NOVELTY - Preparing dispersible ethanolamine functionalized graphene, comprises (i) taking the graphene oxide as raw material, ultrasonically processing to prepare the graphene oxide dispersion liquid, adjusting the pH value of aqueous dispersion acid, adding ethanol, stirring, fully reacting, washing with de-ionized water, filtering, collecting filter residue; and (ii) dispersing the residue in de-ionized water, adding hydrazine hydrate, stirring and reflowing, pumping filtering, washing via microporous filtering film, drying by spraying continuously to obtain the amine functional graphene. USE - The method is useful for preparing dispersible ethanolamine functionalized graphene. ADVANTAGE - The method is simple and the obtained ethanolamine functional graphene can be stably dispersed in various solvent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a dispersible ethanolamine functionalized graphene prepared by the above mentioned method.
