Dispersion/Transfer Free Fabrication of SWCNT Based Flexible, Transparent, and Conductive Films Using Electrostatic Spray Assisted Floating Catalyst Chemical Vapor Deposition

Abstract

In this study, the direct growth of a transparent conductive film consisting of single-walled carbon nanotubes (SWCNTs) on a polyethylene terephthalate (PET) substrate was reported. The SWCNTs were grown using an electrostatic-spray-assisted floating catalyst chemical vapor deposition method, and were deposited on the PET substrate, which was located at the end of the furnace tube. The as-prepared film possessed a sheet resistance of 277 Omega/sq and a 80% transmittance at 532 nm. In addition, the deposited film also had a good adhesion to the PET substrate, as evidenced by the scotch-tape test performed after a HNO3 treatment.
