Lightweight conductive foam : An ultralight conductive nanocomposite foam with a density of 0.05 g cm −3 (see SEM image) was successfully prepared based on multi‐walled carbon nanotubes and rigid polyurethane. An interesting density‐dependent conductor–insulator transition was observed in this ultralight composite, which reveals the weight‐lightening limit of a conductive polymer composite.
