Aerographene

Aerographene is an extremely lightweight material that is often referred to as the world's lightest solid. It is a type of aerogel made primarily from graphene, which is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice. The material is characterized by its low density, high surface area, and excellent electrical conductivity. Aerographene is created through a process that typically involves the removal of liquid from a graphene oxide gel.
