Graphene-based gadgets may be just years away
Date:4/30/2008

hester research team has now demonstrated highly transparent and highly conductive ultra-thin films that can be produced cheaply by dissolving chunks of graphite an abundant natural resource into graphene and then spraying the suspension onto a glass surface.

The resulting graphene-based films can be used in LCDs and, to prove the concept, the research team have demonstrated the first liquid crystal devices with graphene electrodes.

Dr Novoselov believes that there are only a few small, incremental steps remain for this technology to reach a mass production stage. Graphene-based LCD products could appear in shops as soon as in a few years, he adds.

A research team from the Max Planck Institute for Polymer Research in Germany recently reported in Nano Letters how they had used graphene-based films to create transparent electrodes for solar cells (1).

But the German team used a different technology for obtaining graphene films, which involved several extra steps.

The Manchester team says the films they have developed are much simpler to produce, and they can be used not only in LCDs but also in solar cells.
