| 摘要 |
The present invention provides a transition-metal-coated carbon material having a transition metal coating which has a high adhesion strength between the transition metal and the carbon material, and which is neither exfoliated nor detached in subsequent processing. The transition-metal-coated carbon material of the present invention is obtained by adhering a compound containing transition metal ions onto a surface of a carbon material and by reducing the transition metal ions with carbon in the carbon material by a heat treatment, thereby to form elemental transition metal. Here, the transition metal is Fe, Co, Ni, Mn, Cu or Zn. Moreover, the present invention provides a carbon-metal composite material exhibiting an excellent mechanical strength and thermal conductivity, by improving affinity with a metal such as aluminium by use of the transition-metal-coated carbon material. |
