Aerographene or graphene aerogel is, as of April 2024 , the least dense solid known to exist, at 160 g/m (0.0100 lb/cu ft; 0.16 mg/cm ; 4.3 oz/cu yd), less than helium. It is approximately 7.5 times less dense than air. Note that the cited density does not include the weight of the air incorporated in the structure: it does not float in air. It was developed at Zhejiang University. The material reportedly can be produced at the scale of cubic meters. WebGraphene is a two-dimensional carbon allotrope. It is composed of carbon atoms positioned in a hexagonal design, which can be said to resemble a chicken wire. A single layer of carbon atoms arranged in such a …
