Lightweight research - 75x lighter than Styrofoam

They have named it Aerographite and it is jet black. Scientists at Kiel University and Hamburg University of Technology have created the lightest material in the world, it weighs 0.2 milligrams per cubic centimetre. As such it is 75 times lighter than Styrofoam. The material is a network of porous carbon tubes that is three-dimensionally interwoven at the nano and micro levels formed by CVD of graphite on a zinc oxide sacrificial substrate. One potential application of Aerographite being the electrodes of Li-ion batteries. The full publication is available at this link.
