Very thin transparent, conductive carbon nanotube films on flexible substrates

We investigate the morphological, electrical, and optical properties of carbon nanotube thin films, focusing on films with transmittance, T>90%. For films with T≈90% we measure sheet resistance of Rs 90%. Thus, while reducing t can give T>99%, the corresponding Rs increases to >40 kΩ/◻. Acid treatment improves the conductivity by doping, giving properties such as T≈98% for Rs≈10 kΩ/◻.
