1. the preparation method of a graphene/carbon nanometer tube composite materials is characterized in that, comprises the steps:

  • S1, substrate is cleaned up post-drying, subsequently at described substrate surface coated catalysts;

    S2, the described substrate of coated catalysts is put into reaction chamber, after the sealing described reaction chamber is evacuated to 10 -3Below the Pa, the pumpdown time maintains 1~

    30 minute, then to described substrate heating;

    S3, when described underlayer temperature reaches 400~

    700 ℃

    , in described reaction chamber, pass into the reducing gas that airshed is 10~

    1000sccm, and be incubated 1~

    60 minute and reduce described catalyzer;

    S4, continue to pass into described reducing gas when passing into the gaseous carbon source compound in the described reaction chamber, and reacted 1~

    120 minute;

    Underlayer temperature is down to 200~

    300 ℃

    subsequently, makes Graphene;

    S5, then underlayer temperature is heated to 700~

    1300 ℃

    , again in described reaction chamber, passes into described gaseous carbon source compound and reducing gas, and reacted 5~

    120 minutes, make described graphene/carbon nanometer tube composite materials.
