Transparent single-walled carbon nanotubes (SWCNT) based flexible conductive coatings have found great application potentials in flexible displays and solar cells. In this paper we report a simple method for the fabrication of this type of conductive coatings. By using plasma treatment of the flexible polymer substrates, the fabrication of SWCNT flexible coating can be easily achieved through a simple dip coating process. Initial results show that one-dip yields a sheet resistance of 128 ¿/¿ and film transmission of more than 90% at the wavelength of 550 nm, while two-dip produces a coating with a sheet resistance of 75 ¿/¿ and transmission of more than 80% at the wavelength of 550 nm. The performances achieved are comparable to those of the ITO coatings and significantly better than those reported in the literature for the SWCNT coatings produced by using similar methods.
