Abstract

The effect of the addition of n-layer graphene on the physical properties (density, electrical conductivity, thermal conductivity) of copper samples sintered at high pressure and temperature was studied. It was shown that the addition of graphene Gn (4) to copper powder in an amount of 0.2–0.4% (by weight) allows an increase in the value of thermal conductivity of samples by 14–37%. The results obtained indicate the promise of studies on copper doping with n-layer graphene in order to obtain structural materials with increased heat conduction. The obtained experimental data will also be an important component in the development of production technology using high pressure techniques of diamond–copper composites with the addition of n-layer graphene with high thermal conductivity
