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.
