Abstract
The 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.
Claims25
A method for functionalizing carbon nanotubes comprising:
- a) selecting a plurality of carbon nanotubes;
- and b) reacting said plurality of carbon nanotubes at the sidewall carbon atoms with an organic functionalizing agent in the absence of a solvent.
