Graphene aerogel is claimed as 'world's lightest material'

摘要

A new aerogel made from graphene looks set to claim the title of the world's lightest material. Created by a research team from China's Zhejiang University, the aerogel has an ultra low density of just 0.16mg/cm~3, lower than the density of helium and of the aerographite material which until now held the crown. According to the researchers, the material can absorb up to 900 times its own weight in oil, making it attractive for cleaning up oil spills. It is also said to be very strong and extremely elastic. To create the aerogel, the researchers turned to graphene.
