Graphene Aerogel Takes World's Lightest Material Crown

Posted by samzenpus on Monday March 25, 2013 @02:00AM from the I-don't-feel-a-thing dept.

cylonlover writes "Not even a year after it claimed the title of the world's lightest material, aerographite has been knocked off its crown by a new aerogel made from graphene. Created by a research team from China's Zhejiang University in the Department of Polymer Science and Engineering lab headed by Professor Gao Chao, the ultra-light aerogel has a density of just 0.16 mg/cm3, which is lower than that of helium and just twice that of hydrogen."

The density is measured including its interior space. In reality the interior space is filled with air and its realtive weight is the carbon structure alone.
To make it float you would have to find a way to seal off the interior structure and remove the air from that.
