Abstract

The authors developed the protocol to fabricate transparent single wall carbon nanotube (SWCNT) films on polyethylene terephthalate (PET) film via spin coating of SWCNT-dispersion solution in dichloroethane (DCE). As it turned out, preparation of good SWCNT-dispersion solution was essential for making good transparent films with low sheet resistance. The posttreatment with nitric acid was also performed to reduce the sheet resistance of as-prepared films. Our acid-treated SWCNT films showed visible-range transmittance of about 80% at sheet resistance of about 85 Ω/sq.
