Heat transfer in high volume fraction CNT nanocomposites: Effects of inter-nanotube thermal resistance

► Thermal properties of CNT composites simulated with Monte Carlo methods. ► CNT-polystyrene (PS) thermal resistance calculated with matching to experiments. ► Thermal resistance found to increase with temperature. ► CNT-CNT thermal resistance found to be almost 5 times the CNT-PS resistance. ► CNT-CNT thermal resistance is detrimental to heat transfer in high vol.% composites.
