Aerographite: World’s Lightest Solid Material


Researchers at the Hamburg University of Technology and University of Kiel in Germany have created the world’s lightest solid material. Aerographite has a density of 0.2mg per cubic cm. This eclipses the previous lightest material Ultralight Metallic Microlattice, which has a density of 0.9mg per cubic cm. 

The new sponge-like material is made from a network of carbon tubes grown at nano scale, and is 99.99% air. Its material properties include electrical conductivity and the ability to be compressed by a factor of 1,000 before springing back to its original shape. Potential uses for Aerographite include lightweight batteries.
