Abstract
An optically transparent and electrically conductive single walled carbon nanotube (SWNT) film comprises a plurality of interpenetrated single walled carbon nanotubes, wherein for a 100 nm film the film has sufficient interpenetration to provide a 25° C. sheet resistance of less than 200 ohm/sq. The film also provides at least 20% optical transmission throughout a wavelength range from 0.4 μm to 5 μm.
