Carbon nanomaterials have attracted significant attention due to their potential to improve applications such as transistors, transparent conductors, solar cells, batteries, catalysts, and sensors.  This talk will highlight our latest efforts to develop strategies for purifying, functionalizing, and assembling carbon nanomaterials into functional arrays.  For example, we have recently demonstrated and commercialized a scalable technique for sorting surfactant-encapsulated single-walled carbon nanotubes (SWCNTs) by their physical and electronic structure using density gradient ultracentrifugation (DGU).  The resulting monodisperse SWCNTs enhance the performance of thin-film transistors, infrared optoelectronic devices, transparent conductors, photovoltaics, and sensors.  The DGU technique also enables multi-walled carbon nanotubes to be sorted by the number of walls and solution phase graphene to be sorted by thickness, thus expanding the suite of monodisperse carbon nanomaterials.  By extending our DGU efforts to carbon nanotubes and graphene dispersed in biocompatible polymers, new opportunities have emerged for monodisperse carbon nanomaterials in biomedical applications.
