1. the preparation method of a nitrogen replacement graphene oxide/polyaniline composite material is characterized in that, may further comprise the steps:

  • (1) graphite oxide of drying is inserted in the reactor, in reactor, feed the dry ammonia and the gaseous mixture of argon gas and ammonia successively, under 300~

    1000 ℃

    , carry out nitrogen substitution reaction 0.5~

    6h, obtain nitrogen and replace graphite oxide;

    (2) nitrogen that obtains in the step (1) is replaced graphite oxide and join in the dispersant, ultrasonic dispersion obtains nitrogen and replaces graphene oxide;

    (3) in the nitrogen replacement graphene oxide of step (2), drip aniline under the room temperature, continue ultrasonic dispersion and form mixed liquor;

    Under-5~

    10 ℃

    , be added dropwise to oxidant and inorganic acid solution successively subsequently, and continue to stir 1~

    24h, filtering reacting liquid obtains said nitrogen and replaces graphene oxide/polyaniline composite material.
