1. a kind of method of preparation of industrialization big size graphene, it is characterised in that comprise the following steps successively:



  • 1)

    Graphite and concentrated sulphuric acid are mixed to get into mixed solution(

    a)

    , to the mixed solution(

    a)

    Carry out supersound process so that chemical graft and mechanical stripping are carried out simultaneously, and resulting solution includes the Graphene on upper strata and the concentrated sulfuric acid solution of lower floor after ultrasound(

    b)





    2)

    Separating obtained Graphene and concentrated sulfuric acid solution(

    b)



    And(

    3)

    Wash step with water(

    2)

    In the Graphene isolated, Jing filters, is dried to obtain big size graphene.
