🌡️ the best thermal insulators with a melting point of 1200°C
💪 super strong and some can hold a load of up to 2000x its own weight
🪶 the world's lightest solid material

The low density of graphene aerogels makes them very absorbent and they can absorb up to 1000x their own weight in liquid. This could be used in environmental applications such as absorbing off-shore oil spills. In addition, these materials could be used for lightweighting applications.
