Summary:

Thomas Swan Advanced Materials division is devoted to the development of high value materials for emerging technologies. We were early investors in carbon nanotubes and are now a world leading supplier of high purity single wall carbon nanotubes. In collaboration with CRANN (Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN) at Trinity College Dublin) we have developed a new method for exfoliating graphite in liquids to give large-volume dispersions of graphene flakes. This method produces pristine, high conductivity graphene nanoplatelets which will be commercially available in 2014. The graphene materials produced by this process and potential application benefits will be described.
