Graphene is a one-atom-thick sheet of carbon atoms in a honeycomb crystal lattice (hexagons), and is the building-block of Graphite. Graphene is exciting researchers and businesses around the world - as it's strong and thin and possesses very interesting properties. Graphene has a lot of possible applications in the fields of electricity, conductivity, energy generation, batteries, sensors and more.
There are dozens of small companies that are already producing graphene (and graphene-based materials). While production volume is small and prices are still high, we already begin to see some commercial applications that use these materials. Hopefully in coming years production volume will increase and prices will drop which will enable more and more products to use graphene based materials.
Commercial products that use graphene
As we said, while graphene is a relatively new material, applications are starting to appear. The first product to use graphene, as far as we know, is the Siren Technology security smart packaging, which uses Vorbeck Materials's graphene based Ink.
Some companies have announced some graphene based products, we're not sure if these are real yet. Shanghai's Powerbooster Technology claim to have developed a graphene-based flexible touch-panels for mobile devices. They say they are already producing millions of such panels a month, shipping them to mid-sized Chinese smartphone makers. This isn't confirmed yet though.
In the beginning of 2013, HEAD announced their new range of graphene tennis rackets (YouTek Graphene Speed series). These rackets supposedly use graphene to make the shaft stronger and lighter, and HEAD says that the graphene helps distribute the weight better and creates a stronger and better controlled racket. HEAD offers five different rackets, ranging from $170 to $286. It's still not clear what's the material HEAD are using exactly in this product, but it's likely that they are using AGM's graphene flakes.
