Ultralight and highly compressible graphene aerogels

Abstract

Chemically converted graphene aerogels with ultralight density and high compressibility are prepared by diamine-mediated functionalization and assembly, followed by microwave irradiation. The resulting graphene aerogels with density as low as 3 mg cm-3 show excellent resilience and can completely recover after more than 90% compression. The ultralight graphene aerogels possessing high elasticity are promising as compliant and energy-absorbing materials. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
