MIT engineers have fabricated polythene films that conduct heat – not as well as copper (401W/mK), aluminium (237) or aluminium nitride (140–180) but, at 62W/mK, as good as steel and better than alumina (30), and much better than normal polythene which is an insulator at ~0.4W/mK. “We think this result is a step to stimulate ...
