1. a preparation method for graphite oxide, is characterized in that, comprises step as follows:

  • S1, graphite immersed in oxidizing solution and soak 5 ~ 10 minutes, take out graphite;

    On S2, reaction bench that the graphite soaked is tiled in reactor, then in reactor, protective gas is passed into, then microwave irradiation heating 0.5 ~ 5 minute is carried out to the graphite in reactor, be cooled to room temperature subsequently, obtain graphite and graphite oxide mixture;

    S3, again to immerse graphite and graphite oxide mixture described in step S1 oxidizing solution in soak 5 ~ 10 minutes, take out graphite and graphite oxide mixture;

    S4, the graphite soaked step S3 oxidizing solution and graphite oxide mixture repeatedly repeating step S2 ~ S3, till graphite is converted into graphite oxide completely.
