Uniform single-walled carbon nanotube films are fabricated by a DC electrodeposition technique from a dispersion solution of the nanotubes in dry organic solvents. Thick and shiny or thin and see-through, tightly bound films are formed on various substrates (see Figure). Highly efficient deposition is made possible by eliminating water from the dispersion solvent.
