  • Patent number: 10870579
    Abstract: A graphene preparation method includes steps of: thoroughly mixing flake graphite powder with a intercalating agent through electrically string, then adding a reagent solution into a mixture of the flake graphite powder and the intercalating agent and thoroughly stirring for acting, so as to obtain no more than five layers of graphene; wherein the flake graphite powder, the intercalating agent and the reagent solution form a coexistence state of the three electronic phases; electronic phase resonance is induced among the materials, releasing a large amount of energy in the form of vibration and heat across interfaces between layers of carbon atoms, resulting in exfoliation of graphene. The thorough permeation of the intercalating agent ensures the electronic phase resonance can be induced in most layer interfaces, achieving few layer graphene which is equivalent to 5 layers or less.
