▎ 摘　　要

The thermal conductivity of the nanofluids based on water and graphene and water solutions of the nanostructures based on graphene and gold nanoparticles was investigated. It was established that higher values of the thermal conductivity of the nanocomposites based on graphene and gold nanoparticles are the result of the enhancement effect by mean the thermoconductive heavy substrate from gold nanoparticles, which is formed as a result of compatible sedimentation in the water with lighter graphene during the formation of nanocomposites from water solution.
