▎ 摘　　要

NOVELTY - Preparing graphene powder by rapid macromolecule reduction comprises (a) adopting the improved Hummers method to obtain graphite oxide, using pure water for diluting the oxidation product, ultrasonically oscillation or strong stirring process to obtain oxidized graphene acid solution, (b) transferring the oxidized graphene solution into the reaction container, raising the temperature to 40-98 degrees C, under the condition of stirring, adding reducing iron powder, reacting for 1-6 hours, allowing to stand and cooling to 50 degrees C, filtering when it is hot, washing, drying, crushing and sieving. USE - The method is useful for preparing graphene powder by rapid macromolecule reduction (claimed). ADVANTAGE - The method is economical, has no toxicity, is environmentally friendly, requires low energy consumption and suitable for large-scale production.
