Graphene Aerogel Is The World's Lightest Material
Graphene Aerogel is the new world's lightest material created by research team headed by Prof. Gao Chao at Department of Polymer Science and Engineering in China's Zhejiang University. The new material has density of 0.16 mg/cm3. The earlier record was held by aerographite with density of 0.16 mg/cm3. The team used their extensive experience in developing one-dimensional graphene fibers and two dimensional films. Gao and his team added a third dimension to create a popous material from graphene. For the sake of comparison, the new graphene aerogel has density lower than helium, about 2x that of hydrogen.
The team even used a new type of method called 'freeze-drying' to create graphene sponge which can adjust to any shape. The material is not only the lightest, but very elastic and can absorb 900x its own weight in oil. The team proposes that the material can be used to mop up oil spills in the sea.

GurjapAny info about its stiffness? If it's high enough, we could make structural shapes out of it and use them in aeroplanes and ICBMs. -

Nope, it's actually elastic! I doubt it can be used to make structural shapes. This would mostly be used in industrial applications for soaking up oil and liquid stuff, I'd believe.GurjapAny info about its stiffness?

GurjapWell, then maybe if its reactivity is low, chem people can use it to design new, compact packed bed reactors. I wonder if it absorbs hydrogen well..... If it does, we have a potential solution to our hydrogen storage problem.
