The technique of forming thin films of single-walled carbon nanotubes by ultrasonic spraying an aqueous dispersion. The developed technique allows to form a film of single-walled carbon nanotubes of large area and highly homogeneous. The technique allows to form a nanotube coating on the surfaces of complex shape. Using this method, the transparent electrodes are formed characterized by transparency of 77% and a surface resistivity of 210 ohms / square, and transparency in the infrared range of more than 91%.
