Retrieved from https://hdl.handle.net/1911/79981.https://hdl.handle.net/1911/79981The present invention provides methods by which carbon nanotubes can be functionalized under solvent-free conditions. As extremely large quantities are typically required to dissolve or disperse carbon nanotubes, solvent elimination the processes more favorable for scale-up. Such processes are also amenable to a wide variety of chemical reactions are functionalizing agents.18 ppengUtility patentUS7459137B2
