New polymer films conduct heat instead of trapping it

Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat -- an ability normally associated with metals. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than many metals, including steel and ceramic.
