CARBON NANOTUBE FILMS AND METHODS OF FORMING FILMS OF CARBON NANOTUBES BY DISPERSING IN A SUPERACID

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 pe...

Zusammenfassung:	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.
