Copper-clad carbon nano composite wire and preparation method thereof

The invention discloses a preparation method of a copper-clad carbon nano composite wire. The composite wire core is prepared by taking carbon nano tubes as a core layer and the copper layer as an outer layer, wherein the carbon nano tubes and the copper layer are tightly combined together through the treatment process of raw material pretreatment, polishing, wire blank cladding and welding, drawing and cladding and baking in sequence, so that the prepared copper-clad carbon nano composite wire has relatively high mechanical property and conductivity. 本发明公开了一种铜包碳纳米复合线的制备方法，通过将碳纳米管作为芯层、铜层作为外层制备复合线芯，并依次经过原料的预处理-打磨-包覆焊接线坯-拉拔-包覆烘焙的处理工艺，使碳纳米管和铜层紧密结合在一起，使所制备的铜包碳纳米复合线同时具备较高的机械性能和导电性能。
