| Routes to functionalization and characterization of carbon nanotubes will be discussed. This will include a solvent-free process that makes the functionalized systems accessible at low cost, and methods for the functionalization of individualized single-wall nanotubes in fuming sulfuric acid. Blending <1 wt % of these functionalized materials into commodity elastomers can increase the tensile modulus several-fold, while retaining the original elongation-to-break properties. Secondly, blending 1 wt % nanotubes into commodity plastics, followed by short (3 second) exposure to low power microwaves (60 W) can result in crosslinks at the exposed locations for localized modulus changes. Thirdly, processes have been developed for the functionalization of the metallic tubes, thereby providing a handle for the separation from the semiconducting species. And finally a route to seeded nanotube growth will be described wherein we seek a protocol for the synthesis of only a single tube type, thereby having absolute control over nanotube helicity and diameter. |
