Abstract

The structure and properties of a copper–n-layer graphene composite obtained under high-pressure and high-temperature (HPHT) conditions were studied depending on the method of mixing the mixture components using a Pulverisette 6 classic line ball mill, an EXAKT three-roll mill, and manual mixing. It was established that, regardless of the method of mixing the components, the addition of n-layer graphene increased the thermal conductivity of the composite compared to pure copper. The highest thermal conductivity (559 W/(m K)) was exhibited by a composite sintered from a mixture obtained by manual mixing due to the uniform distribution of the components in the mixture and to minimization of the plastic deformation of copper particles during the mixing.
