Transparent conductive single-walled carbon nanotube (SWNT) film was fabricated by spraying onto polyethylene terephthalate (PET) substrates coated with a thin polymethyl methacrylate (PMMA) layer. The PMMA layer of a thickness ~1 ¿m was used as an adhesion promoter between the PET substrate and the SWNTs. The electrical conductivity of SWNT film was improved by treatments in nitric acid (HNO3) and thionyl chloride (SOCl2). The SWNT film obtained through this manufacturing method showed a sheet resistance of 150 ¿/sq with a transmittance of 80%. The film also revealed a high adhesion on the substrate, and the resistance change with the bending angle was small.
