Graphene Aerogels

Graphene aerogel is synthetic material having high porosity and low density. Graphene aerogel is produced through the reduction of precursor graphene oxide solution leading to the formation of graphene aerogel. The solvent is removed from the poles through the process of freeze-drying, where it is replaced with air. Graphene aerogel has enhanced mechanical properties because of its structure and morphology. It has Young's modulus on the order of 50 MPa, where it can be compressed to strain values >50%. It has the potential to replace flight balloons. They are also used on offshore oil cleanup and to gather dust from the tails of comets.
