The utility model discloses a carbon nano-tube composite film for the laser driving flying plate technology. The composite film comprises an absorption layer, wherein an ablation layer is arranged on the absorption layer; a heat insulation layer is arranged on the ablation layer; a flying plate layer is arranged on the heat insulation layer; the absorption layer is made of a carbon nano-tube array film, the diameter of each carbon nano-tube in the carbon nano-tube array film is within 0.2 micron, and the thickness of the carbon nano-tube array film is within 0.3 micron. The carbon nano-tube composite film has the beneficial effects of effectively avoiding the phenomenon of disordered expansion of the graphite absorption layer under laser ablation, remarkably improving the energy conversion efficiency of laser driving flying plates, and promoting the flying plate speed.
