▎ 摘  要

NOVELTY - The method comprises primarily irradiating electron beam on graphite for peeling pure graphite, immersing the pure graphite in sulfuric acid, washing the graphite and then removing remaining impurities by filtering, and performing ultrasonication on the graphite with surfactant. A total exposure of the electronic beam irradiated in the graphite is 1-5000 kilogray. The electron beam comprises gamma rays, electron beams, ion beams, neutron beams and UV rays. USE - The method is useful for preparing graphene (claimed). ADVANTAGE - The method is capable of preparing the graphene in an effective and environmentally friendly manner with less amount of chemicals and without damages.
