In this invention, processes which can be used to achieve stable doped carbon nanotubes are disclosed. Preferred CNT structures and morphologies for achieving maximum doping effects are also described. Dopant formulations and methods for achieving doping of a broad distribution of tube types are also described.

Modified carbon nanotubes and methods of forming carbon nanotubes

A novel method of forming thin films of carbon nanotubes (CNTs) is described. In this method, carbon nanotubes are dispersed in a superacid solution and laid down on a substrate to form a conductive and transparent CNT network film. The superacid, in its deprotonated state, is an anion that has a permanent dipole moment. The superacid solution may be a pure superacid or have additional solvent. Preferably, the superacid solution does not contain an oxidizing agent. Novel, highly conductive and transparent CNT network films are also described.
