1. a preparation method for fluorinated graphene, is characterized in that, comprises the steps:

  • Graphite is provided;

    Use described graphite-made for graphene oxide;

    Described in liquid-phase reduction, graphene oxide makes Graphene;

    Graphene reacts and makes fluorinated graphene with fluorine-containing material;

    It is cooling after described Graphene and fluorochemicals are processed 1~

    10h taking mass ratio as 1;

    1~

    1;

    100 at 200~

    1000 DEG C that described Graphene reacts with fluorine-containing material, and water and washing with alcohol, dry, obtain described fluorinated graphene successively;

    The step that described in liquid-phase reduction, graphene oxide makes Graphene comprises;

    Described graphene oxide is mixed with deionized water and be dispersed into suspension liquid;

    In described suspension liquid, add reductive agent, 90~

    100 DEG C of thermal reduction 24~

    28h obtain Graphene suspension liquid;

    After filtering, described Graphene suspension liquid collects filter residue, and dry after water, methanol wash successively, obtain described Graphene;

    Described fluorochemicals is at least one in Neutral ammonium fluoride, Sodium tetrafluoroborate, potassium fluoborate, potassium fluoroaluminate and Sodium Silicofluoride.
