Ultralight Conductive Carbon‐Nanotube–Polymer Composite

Abstract

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.
