1. the preparation method of a fluorinated graphene/polyaniline matrix material comprises the steps:

  • Step 1, provide the fluorinated Graphene;

    Step 2, described fluorinated Graphene is joined in the alcohols dispersion agent, ultra-sonic dispersion forms homodisperse fluorinated Graphene solution;

    Step 3, add aniline in described fluorinated Graphene solution, ultra-sonic dispersion forms homodisperse mixed solution;

    Step 4, under-5~

    10 ℃

    , the described alcohols dispersant solution of dropping oxidizing agent and mineral acid successively in the described mixed solution stirs, polymerization reaction take place obtains reaction mixture;

    Step 5, with described reaction mixture centrifugation, get solid and the washing, obtain described fluorinated graphene/polyaniline matrix material after the drying;

    The described fluorinated Graphene that step 1 provides makes as follows;

    Graphite is provided;

    Described graphite, Potassium Persulphate and Vanadium Pentoxide in FLAKES joined according to mass ratio 2;

    1;

    1 in 60~

    85 ℃

    the vitriol oil, the back naturally cooling that stirs, washing is dry to neutral back, obtains pretreated mixture;

    Described pretreated mixture and potassium permanganate are joined temperature be lower than in 20 ℃

    the vitriol oil, then at 30~

    40 ℃

    of following oil bath 1.5~

    2.5h, add deionized water, add the hydrogen peroxide reaction behind the 15min, suction filtration, collect solid;

    Described solid washs with dilute hydrochloric acid, and drying obtains described graphene oxide;

    Described graphene oxide and F 2Volume fraction be 5~

    30% by N 2And F 2The mixed gas of forming reacts 0.5~

    24h down at 20~

    200 ℃ and

    makes described fluorinated Graphene.
