Abstract:
1. An optically transparent and electrically conductive single walled carbon nanotube (SWNT) film, comprising a plurality of single walled carbon nanotubes (SWNTs), wherein the film has uniform nanotube density across said film's area with the nanotube's surfaces being free of residual stabilizing agents allowing intimate electrical contact between the nanotubes throughout said film, and the film is less than 1,000 nm thick, and wherein at a thickness of 100 nm the film has sufficient interpenetration to provide a 25° C. sheet resistance of less than 200 ohm/sq and at least 20% optical transmission throughout a wavelength range from 0.4 μm to 40 μm.
