Introduction
What do you get if you make a material from predominantly air entrapped within a very fine structure of porous carbon nanotubes?
You get one of the worlds lightest materials - Aerographite.
Scientists from Kiel University (KU) and Hamburg University of Technology (TUHH) have created the new material 'Aerographite' by carefully growing an interlinking chain of Carbon nanotubes within a sacrificial template made from Zinc Oxide. Creating a network of porous carbon tubes three-dimensionally interwoven at nano and micro level.
Weighing in at only 0.2 milligrams per cubic centimetre, Aerographite is officially the lightest material in the world - reported to be 75 times lighter than Styrofoam! Not only is this material extremely light, it is also extremely strong, based largely on the unique properties of Carbon Nanotubes, but also on the innovative structure of the material.
Properties of Aerographite
Aerographite is extremely lightweight but it also has a number of interesting properties. Including:
Electrically conductive
Highly ductile
Compressible
Non-transparent - Jet black appearance
Extremely strong
Is chemically stable
