Definitions
- the present invention relates to a method for producing a carbon-based particle / copper composite material in which carbon-based particles such as graphite and copper are mixed with each other.
- Copper is widely used in various fields because of its good thermal conductivity and low electrical conductivity. Copper is often used as its own material, but for various reasons, copper is mixed with carbon-based particles such as graphite, SiC, and carbon nanotubes to form a composite material, and in particular, as a heat sink. The use case increases.
- the mixed state of carbon-based particles and copper is very important. If the mixed state of both materials is poor and each component is present separately, physical properties resulting from the compounding of both materials cannot be obtained, and the mechanical properties are also reduced.
- carbon-based particles and copper have poor compatibility because their material properties are different from each other. Therefore, it is difficult to obtain a composite material in which carbon-based particles and copper are well mixed with a common carbon-based particle / copper composite material manufacturing method such as a liquid phase sintering method and a simple impregnation method.
- the method for producing a composite material of carbon-based particles / copper is a method for producing a composite material of carbon-based particles / copper

- the polymer organic compound increases the miscibility between the cuprous oxide particles and the carbon-based particles, and the cuprous oxide particles are formed on the surface of the carbon-based particles. Attached composite intermediates can be obtained. By reducing the composite intermediate, it is possible to obtain a composite material in which carbon-based particles and copper are well mixed, and thus may be usefully used as a heat sink.

- the injected first reducing agent acts on the copper precursor to form cuprous oxide particles.
- the cuprous oxide particles are formed in a form that is physically attached to the surface of the carbon-based particles, thereby functioning as an intermediate capable of forming a composite material in which the carbon-based particles and copper are well mixed.
- the reason why the composite particles are formed in such a way that the cuprous oxide particles adhere to the carbon-based surface is presumably due to the polymer organic compound dissolved in the mixed product.
- the polymer organic compound Since the main chain is made of carbon, the polymer organic compound has good compatibility with carbon-based particles.
- polyvinylpyrrolidone or polyvinyl alcohol is preferably selected in view of such miscibility. Since the polymer organic compound dissolved in the mixed product partially or entirely covers the surface of the cuprous oxide particles to be formed, it is determined that the cuprous oxide particles are easily attached to the surface of the carbon-based particles.
- the first reducing agent may be used as long as it can act on a copper precursor to form cuprous oxide particles.

- the above patent is incorporated herein by reference.
- the cuprous oxide particles are reduced to copper to obtain a composite material of carbon-based particles / copper (step 3). Since the cuprous oxide particles are reduced to copper in a state where they are attached to the surface of the carbon-based particles, the resulting carbon-based particles / copper composite material is well mixed with the carbon-based particles and copper.
- the non-oxidizing atmosphere may be any atmosphere in which cuprous oxide particles are reduced to copper, such as an inert gas atmosphere such as nitrogen, a vacuum atmosphere, and a reducing gas atmosphere such as hydrogen.
- step. 3 may be replaced by the following method. That is, step.
