Abstract

A carbon-based aerogel is disclosed in which the carbon atoms are arranged in a sheet-like nanostructure. The aerogel may be either a graphene oxide aerogel or a graphene aerogel and may further be reinforced with a polymer. A method for making the aerogel is also disclosed and includes providing graphite oxide, creating a dispersion of the graphite oxide in a liquid, and drying the dispersion to form a graphene oxide aerogel. In one embodiment, the graphene oxide aerogel is thermally treated to convert the graphene oxide to graphene.
