Aluminum matrix directional carbon nano tube copper plating composite radiating material and preparation method

The invention provides an aluminum matrix directional carbon nano tube copper plating composite radiating material and a preparation method. The aluminum matrix directional carbon nano tube copper plating composite radiating material is composed of copper, aluminum and a carbon nano tube; the carbon nano tube grows on the aluminum to form a directional array; and the copper grows on the carbon nano tube to form a carbon nano tube/copper moniliform structure so as to obtain the aluminum matrix directional carbon nano tube copper plating composite radiating material. An aluminum/carbon nano tube/copper three-dimensional heat transmission pathway is constructed to make up the respective radiating defect of copper, aluminum and the carbon nano tube, and copper, aluminum and the carbon nano tube are cooperated to play the advantages to obtain the composite radiating material with high heat conductivity. 本发明提供了一种铝基定向碳纳米管镀铜复合散热材料及制备方法，该复合材料由金属铜、铝和碳纳米管组成，所述碳纳米管生长在铝上，形成定向阵列，铜生长在碳纳米管上，形成碳纳米管/铜串珠状构造，制备得到铝基定向碳纳米管镀铜复合散热材料
