NOVELTY - Preparing graphene/metal composite material comprises e.g. taking the metal bar and the high-purity carbon rod, where the high-purity carbon rod mass percentage of between 1-30%, providing the two ends of the metal cleaning respectively on the clamping head and the lower clamping head of drawing system in the floating zone-melting directional solidification furnace and the metal rod coaxial with the drawing system, clamping the high-purity carbon rod in the floating zone-melting directional solidification drawing system side of the clamp so that the high-purity carbon rod forming an acute angle with the metal rod, and the bottom end of the high-purity carbon rod and the melting of the metal contact, providing the floating zone melting directional solidification furnace, controlling melting zone length at 1-50 mm, and rotating along the axis of the drawing system, and moving the bar to the bottom, reducing the heating power to zero immediately, taking out after cooling. USE - The method is useful for preparing graphene/metal composite material. ADVANTAGE - The material has good two-phase interface bonding. The method improves the conductivity of the material. DETAILED DESCRIPTION - Preparing graphene/metal composite material comprises (i) taking the metal bar and the high-purity carbon rod, where the high-purity carbon rod mass percentage of between 1-30%, (ii) providing the two ends of the metal cleaning respectively on the clamping head and the lower clamping head of drawing system in the floating zone-melting directional solidification furnace and the metal rod coaxial with the drawing system, clamping the high-purity carbon rod in the floating zone-melting directional solidification drawing system side of the clamp so that the high-purity carbon rod forming an acute angle with the metal rod, and the bottom end of the high-purity carbon rod and the melting of the metal contact, (iii) providing the floating zone melting directional solidification furnace, the metal rod to the floating zone melting directional solidification, controlling melting zone length at 1-50 mm, the melting temperature is higher than the melting point of the metal, the metal bar moving from up to down for 1-5000 at a speed of mu m/second, and rotating along the axis of the drawing system, the bottom end of the high-purity carbon rod is always in the melting of the metal, and (iv) moving the bar to the bottom, reducing the heating power to zero immediately, taking out after cooling. An INDEPENDENT CLAIM is also included for composition, comprising a metal and high-purity carbon, the high pure metal and the carbon form a single phase, the high-purity carbon exists in the form of graphene in the lattice of the metal.
