NOVELTY - The preparation method of graphene involves weighing graphite powder, removing impurities and then drying, adding paraffin as graphene surface-protective agent to the dried powder and then uniformly mixing, grinding the mixture at 60-100 degrees C and then ball milling at 20-50 rpm, heating the mixture and then grinding, dispersing the mixture in liquid paraffin and then streaming at high-pressure, atomizing the mixture, and cooling. USE - The method is useful for preparation of graphene, which is useful in plastic and rubber. ADVANTAGE - The method enables simple and economical preparation of graphene with excellent stability and dispersibility.
