▎ 摘　　要

NOVELTY - A graphene material is synthesized by mixing dodecylamine-ethanol, ferrous chloride and ammonium dihydrogen phosphate at 45-55 degrees C, centrifuging, drying, grinding, putting in crucible at 40-60 degrees C, vacuum drying for 12-36 hours, adding phenol-ethanol solution, mixing, vacuum drying at 40-60 degrees C for 12-72 hours, calcining in tubular furnace under argon protective atmosphere at 600-900 degrees C for 6-24 hours, treating with concentrated hydrochloric acid, heating at 160-200 degrees C for 24-48 hours, centrifuging, washing by water or anhydrous ethanol, and vacuum drying at 40-60 degrees C for 12-24 hours. USE - Method for synthesizing graphene material (claimed). ADVANTAGE - The method is simple and fast.
