An ultralight graphene structure for all seasons

Published in Chemistry World, 12 Oct 2012

Chemists in China claim to have created the lightest graphene framework to date. The material, which is light enough to rest on a dandelion seed head, is also fire resistant and has record-breaking adsorption and capacitance.

The development of ultralight materials has exploded in recent years. Last year, engineers in the US presented a material made of hollow metallic tubes in a micro-lattice. With a density of 0.9mg/cm3, the material was 100 times lighter than styrofoam. Yet that record was beaten in July, when material scientists in Germany produced what they called aerographite: a network of carbon microtubes with a density of just 0.2mg/cm3. […]
