1. the preparation method of an oriented growth carbon nano-fiber array, it is characterised in that adopt following steps:

  • (1) catalyst is first prepared, by standby after tagger surface treatment, then copper sulfate solution is configured, using this solution as displacement liquid, tagger after process immerses in described copper sulfate solution, carries out displacement reaction, and reaction temperature is room temperature, dip time is 5-8 second, obtains the surface tagger with nanometer copper mold;

    (2) take the surface that a certain amount of step

         1) prepares and be placed in porcelain boat with the tagger of copper mold, porcelain boat is put into the quartz ampoule of heating furnace, to quartz ampoule evacuation, be subsequently passed carbon-source gas acetylene to atmospheric pressure;

    (3) begin to warm up, after heating occurs to reaction, keep constant temperature time 18-22 minute, then turn off heating;

    (4) take out product after naturally cooling to room temperature, obtain carbon nano-fiber array。
