A network of porous carbon tubes that is three-dimensionally interwoven at nano and micro level—this is the lightest material in the world. It weights only 0.2 mg per cubic centimetre, and is therefore 75 times lighter than Styrofoam, but it is very strong nevertheless. Scientists of Kiel University (KU) and Hamburg University of Technology (TUHH) have named their joint creation “Aerographite”. The scientific results were published as the title story in the scientific journal Advanced Materials on July 3.
The properties:
It is jet-black, remains stable, is electrically conductive, ductile and non-transparent. With these unique properties and its very low density the carbon-made material “Aerographite“ clearly outperformes all similar materials.
“Our work is causing great discussions in the scientific community. Aerographite weights four times less than world-record-holder up to now,” says Matthias Mecklenburg, co-author and Ph.D. student at the TUHH. The hitherto lightest material of the world, a nickel material that was presented to the public about six months ago, is also constructed of tiny tubes. Only, nickel has a higher atomic mass than carbon.
