Transparent Conducting Films Based on Carbon Nanotubes: Rational Design toward the Theoretical Limit

Abstract: Electrically conductive thin-film materials possessing high transparency are essential components for many optoelectronic devices. The advancement in the transparent conductor applications requires a replacement of indium tin oxide (ITO), one of the key materials in electronics. ITO and other transparent conductive metal oxides have several drawbacks, including poor flexibility, high refractive index and haze, limited chemical stability, and depleted raw material supply. Single-walled carbon nanotubes (SWCNTs)… Show more

“…We use the generally accepted ratio of intensities for G and D modes of Raman spectra as a figure of quality (as the G band corresponds to vibrations of graphitic lattice, while the D band appears only for distortions in the ideal lattice) [ 30 , 31 , 32 , 33 ]. The equivalent sheet resistance serves as a key performance index for transparent conductors [ 34 ], indirectly describes the length, defectiveness, and diameter of carbon nanotubes [ 35 ], and corresponds to the sheet resistance of a film with 90% transmittance at 550 nm.…”

“…Besides, the search for oxidation agents for the gas-phase post-treatment of SWCNT aerosol focused on the selective etching of semiconducting species might be helpful. The importance of the mentioned methods is highlighted by theoretical calculations on the limits of SWCNT TCF performance, showing long and ideally-ordered armchair nanotubes may exhibit R90 below 100 mΩ/□ [65].…”

“…Therefore, it is deemed to be a preferable technology for SWCNT thin-film production on an industrial scale. It is worth mentioning that the aerosol CVD method provides SWCNT with noticeable better transparent conductive properties compared to other methods [65]. Usually, as a metric of transparent and conductive properties a combination of sheet resistance (𝑅 ) and transmittance (𝑇) in the visible range (e.g.…”

“…[5][6][7] Poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonic acid) (PEDOT:PSS), [8][9][10][11][12] polyaniline (PANI), [13,14] DOI: 10.1002/macp.202200365 polypyrrole (PPy), [15,16] and other intrinsic conductive polymers are commonly used conductive materials. Compared with other types of conductive materials such as metal nanowires [17,18] and carbonaceous materials, [19][20][21] conductive polymers have a variety of chemical structures and microor nano-morphologies, and their physical and chemical properties can be designed and controlled as needed. However, conductive polymers tend to slip against the substrate during stretching, especially under large strain.…”
