“…A number of researchers, relying on high thermophysical properties of carbon nanomaterials, have used in their works carbons nanotubes, [6,7], mixtures of carbon nanotubes and montmorillonite, [9] graphene [11,12]. Thermal conductivity of some carbon nanotubes can be above 3000 W/mK [16], and for diffident types of graphene it is in the range of 500 to 5000 W/mK [11].…”
