NOVELTY - The method for preparing graphene using epoxide grafted hydrazine involves adding solvent to reaction vessel, then adding hydrazine compound, catalyst and epoxy compound (I), stirring and reacting the mixture and then cooling to obtain epoxide grafted hydrazine (II) as reducing agent, preparing graphite oxide by adopting Hummers method to obtain graphene oxide product, adding graphene oxide product to solvent, ultrasonically dispersing, then adding epoxide grafted hydrazine, refluxing and reacting. USE - The method is useful for preparing graphene. ADVANTAGE - The method enables simple preparation of graphene with excellent reducibility and dispersibility. DETAILED DESCRIPTION - The method for preparing graphene using epoxide grafted hydrazine involves adding solvent to reaction vessel, then adding hydrazine compound of formula: R-NH-NH2, catalyst and epoxy compound of formula (I), stirring and reacting the mixture at certain temperature and pressure for certain period of time and then cooling to room temperature to obtain epoxide grafted hydrazine of formula (II) as reducing agent, preparing graphite oxide by adopting Hummers method to obtain graphene oxide product, adding graphene oxide product to solvent, ultrasonically dispersing, then adding epoxide grafted hydrazine, refluxing and reacting at certain temperature for certain period of time and then washing with anhydrous ethanol and deionized water to neutral, centrifugally separating, freeze-drying, heating and evaporating to remove the solvent. R-R1=1-20C alkyl, aryl, ester group, double bond, alkoxy silicon group, nitro or halo;and n=1-10.
