A group of researchers from Zhejiang University’s Department of Polymer Science and Engineering have developed graphene aerogel, and it’s less dense than air. That’s right, a sample of graphene aerogel a few centimeters across is so light that it can be supported by plants. Continue reading for a video and more information.
Geek.com reports that “the Zhejiang University lab, led by Professor Gao Chao, created this material by expanding on techniques previously used to make two-dimensional graphene films. This is the key to the incredible lightness of the materials. Graphene is composed of a single layer of carbon atoms, and researchers found they could simply use a freeze drying process to stack them in three-dimensions.”
