 Single-walled carbon nanotubes dispersed in deionized water with sodium dodecyl benzene sulfonate were sprayed on UV and plasma treated polyethylene terephthalate to achieve transparent conductive films with excellent adhesion. The carbon nanotube films were further treated with different concentrations of nitric acid and characterized by adsorption spectra, Raman spectroscopy, four-point probe method and field-emitting scanning electron microscopy. The results demonstrated that the conductivity of carbon nanotube films with high transparency was improved to a greater degree with higher concentration of nitric acid due to effectively removing residual surfactants.
