Aerographite Breaks Record As Worlds Lightest Material

Aerographite Breaks Record As Worlds Lightest Material

Scientists develop new lightest material in the world…

Scientists at the HRL Laboratories in Malibu have developed a synthetic foam that breaks the record as the worlds lightest material ever created.

The new material has a density of just 0.2 milligram per centimeter – 5 times less than previous contenders.

The foam, known as Aerographite, consists of an interconnected network of carbon nanotubes that are made using a processed called chemical vapor deposition.

To do the joint team from at the Hamburg University of Technology and the University of Kiel, in Germany, first create a ‘scaffold’, which is made by mixing Zn and polyvinyl butral powders and heating the mixture at 900 degree Celsius.

The scaffolding is placed in a reaction chamber under an argon gas flow at -760 degrees Celsius. The aerographite tubes are then grown by injecting carbon rich toulne vapors into the chamber.

The carbon essentially coats the ZnO scaffolding, which is etched away by adding hydrogen gas to the reaction chamber.

The synthetic foam is the latest to the up the stakes in the race to develop lighter and stronger materials which can be used for a wide range of applications from building

Other lightweight materials that had previously topped the bill of being the worlds lightest include Aerogel, a silica or carbon based material with a density of just 1 milligram per centimeter cubed that was used by NASA to collect space dust, and more recently the metallic microlattice, developed by Tobias Schaedler of HRL Laboratories in Malibu, which has a density of 0.9 milligram per centimeter cubed.

These new generation of super lightweight materials are paving the way for super conductors, thermal insulations, batteries, military, aerospace, construction development and even sports – Dunlop already use Aerogel in some of its tennis rackets.
