Over the past three decades, the discovery of new forms of zero-, one- and two-dimensional forms of carbon (i.e. fullerenes, nanotubes, and graphene respectively) have attracted considerable attention due to their unique electronic, optical, mechanical, thermal and chemical properties.  Due to the highly delocalized electronic structure of sp2 hybridized carbon, carbon nanotubes and graphene exhibit high carrier mobilities, making them attractive for electronic applications.  Furthermore, the ability to disperse these nanocarbons in aqueous and organic solvents enables device fabrication via rapid, low cost processes such as printing.  In this talk, I will review progress in processing and characterization of nanocarbon materials as well as their application in printable/flexible electronic devices.  Work at the NRC aimed at developing processes and materials for fully printed thin film translator based on networks of semiconducting single wall carbon nanotubes as the channel material, will be described.  Development of methods for evaluating graphene films formed via solution-processable route will also be discussed.
