Fabrication of two transparent double-wall carbon nanotube (DWNT) thin films produced by a scalable draw-down Meyer rod coating technique on 120 μm thick polyethylene terephthalate (PET) substrates.

(a) Photograph of the scalable draw-down rod coating technique. (b) Transmittance as a function of position along the sample for the transparent DWNT thin films with nominally 80% and 70% transmittance at a wavelength of 550 nm. The uncertainty in the transmittance was approximately the size of the data circle. (c) Atomic force microscopy images of the DWNT thin films on the PET substrate.
