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.
