“…The purified SWCNTs were well dispersed in 1,2-dichloroethane (DCE) solvent without additives [14,16,17]. The low vaporization temperature of DCE (83.5°C) allows more SWCNT to be deposited on the substrate.…”

“…Consequently, the fabrication of flexible TCFs with CNTs has recently been carried out. These recent studies have shown that the electrical conductivity and optical transmittance of CNT films varies, depending on the coating methods and the intrinsic properties of the CNTs [4][5][6][7][8][9][10][11][12][13][14]. In general, the performance of CNT-based TCFs are typically governed by the inherent properties of the CNTs, such as purity, defect concentration, and electrical conductivity.…”

“…In this study, we microscopically and macroscopically evaluated the performance of TCFs to elucidate performance-determining factors, by using experimental results of single-wall CNTs (SWCNTs)-coated TCFs on flexible polyethylene terephthalate (PET) film prepared by dip-coating process [14].…”

Flexible transparent conducting films (TCFs) were fabricated by dip-coating single-wall carbon nanotubes (SWCNTs) onto a flexible polyethylene terephthalate (PET) film. The amount of coated SWCNTs was controlled simply by dipping number. Because the performance of SWCNT-based TCFs is influenced by both electrical conductance and optical transmittance, we evaluated the film performance by introducing a film property factor using both the number of interconnected SWCNT bundles at intersection points, and the coverage of SWCNTs on the PET substrate, in field emission scanning electron microscopic images. The microscopic film property factor was in an excellent agreement with the macroscopic one determined from electrical conductance and optical transmittance measurements, especially for a small number of dippings. Therefore, the most crucial factor governing the performance of the SWCNT-based TCFs is a SWCNT-network structure with a large number of intersection points for a minimum amount of deposited SWCNTs.

“…(2) Spray coating: The CNT solution is sprayed on the substrate with an airbrush and heated to dry the CNT droplets. This simple, low-cost method [40][41] is also suitable for the fabrication large area CNT films. Figure 4(b) shows the schematic of the spray coating method and the SEM image of the CNT film spray coating on the substrate.…”
