The synthesis was accomplished by the freeze-drying of carbon nanotube solutions[4] and large amounts of graphene oxide.
[citation needed] Graphene aerogels are synthetic materials that exhibit high porosity and low density.
[6] Graphene aerogels exhibit enhanced mechanical properties as a result of their structure and morphology.
[5] The mechanical properties of graphene aerogel have been shown to depend on the microstructure and thus varies across studies.
Computational simulations show that graphene walls bend when a tensile or compressive stress is applied.
[8] The macroscopic geometric structure of the aerogel has been shown both computationally and experimentally to affect mechanical properties observed.
[7] Due to the high porosity and low density, graphene aerogel has been explored as a potential replacement in flight balloons.
