Active thermal interface graphene nanocomposites for thermal control of electronic and power devices

Abstract

New experimental and calculated data are presented for active thermal interface materials, in which heat is removed not only due to high thermal conductivity, but also due to the evaporation of liquids, for example, water, inside a nanoporous graphene structure. It is shown that such active thermal interfaces may be new systems of active thermal control.

“…It is noted that the rate of evaporation from the free surface of water is several times lower than from the surface of the graphene layer. The difference can be from 2.5 to 8 times with heat fluxes in the range from 50 to 180 kW/m2 (water enters the layer due to strong absorption by capillaries through the lower part of the graphene layer) [14].…”
