Abstract
Graphene/metal nanocomposite powder and a method of preparing the same are provided. The graphene/metal nanocomposite powder includes a base metal and graphenes dispersed in the base metal. The graphenes act as a reinforcing material for the base metal. The graphenes are interposed as thin film types between metal particles of the base metal and bonded to the metal particles. The graphenes contained in the base metal have a volume fraction exceeding 0 vol % and less than 30 vol % corresponding to a limit within which a structural change of the graphenes due to a reaction between the graphenes is prevented.

Graphene/metal nanocomposite powder comprising:
- a base metal;
- and
- graphenes dispersed in the base metal and acting as a reinforcing material for the base metal,
- wherein the graphenes are interposed as thin film types between metal particles of the base metal and bonded to the metal particles, and
- the graphenes contained in the base metal have a volume fraction exceeding 0 vol % and less than 30 vol % corresponding to a limit within which a structural change of the graphenes due to a reaction between the graphenes is prevented.
A method of manufacturing graphene/metal nanocomposite powder, comprising:
- (a) dispersing a graphene oxide in a solvent;
- (b) providing a salt of a metal as a base metal to the solvent in which the graphene oxide is dispersed;
- and
- (c) forming powder in which graphenes are dispersed as thin film types between metal particles of the base metal by reducing the graphene oxide and the salt of the metal,
- wherein the dispersed graphenes act as a reinforcing material for the base metal and are controlled to have a volume fraction exceeding 0 vol % and less than 30 vol % corresponding to a limit within which a structural change of the graphenes due to a reaction between the graphenes is prevented.
