Claims14
Graphene/ceramic nanocomposite powder comprising:
- a matrix ceramic;
- and
- graphene dispersed in the matrix ceramic.
A preparation method of graphene/ceramic nanocomposite powder, comprising:
- (a) dispersing graphene oxide in a solvent;
- (b) introducing a metal salt which can be converted into a matrix ceramic, into the solvent in which the graphene oxide is dispersed to obtain a reaction mixture;
- and
- (c) performing a heat treatment of the reaction mixture to reduce the graphene oxide to calcine the metal salt to form graphene/ceramic nanocomposite powder including the graphene dispersed in the matrix ceramic.
