Fabrication of durable and flexible single-walled carbon nanotube transparent conductive films

Abstract

Highly flexible, durable, and transparent conducting films are fabricated from the de-bundled SWCNTs in aqueous solutions of SPES with high conductivity (125 Ω sq−1) and good transmittance (87%) without adopting any binder or post treatment techniques.

Sandwich assembly of sulfonated poly (ether sulfone) with sulfonated multiwalled carbon nanotubes as an efficient architecture for enhanced electrolyte performance in H 2 / O 2 fuel cells

“…The I D /I G ratio for SMWCNT is higher than the parental MWCNT signifying the property of MWCNT at the surface was damaged by introducing sulfonic acid moieties on the sp 2 carbon network. 49 XPS spectra of SMWCNT illustrated the surface elemental composition and chemical valences of the functional groups of sulfonic acids occupied on the surface of MWCNT (S2p) and its inherent groups (C1s and O1s) in which is connected to sulfonic acids, that confirms the sulfonation on MWCNT. 45 The surface atomic concentration of sulfonic acid functionalized MWCNT was estimated to be 86.19, 12.28 and 1.53 at% for C1s, O1s and S2p elements.…”

In Silico Study of the Influence of Various Substrates on the Electronic Properties and Electrical Conductivity of Mono- and Bilayer Films of Armchair Single-Walled Carbon Nanotubes

“…One of the most relevant topics in modern science and engineering is the search for thin flexible conductive films for different applications in electronics. At present, carbon nanotubes (CNTs) are the most promising materials for creating such films [1][2][3][4][5][6][7][8][9][10]. As is known, CNT-based thin films with a thickness in the range of 1-100 nm have high electrical conductivity, transmittance, flexibility and stretchability [2].…”

“…At present, carbon nanotubes (CNTs) are the most promising materials for creating such films [1][2][3][4][5][6][7][8][9][10]. As is known, CNT-based thin films with a thickness in the range of 1-100 nm have high electrical conductivity, transmittance, flexibility and stretchability [2]. In addition to these properties, CNT-based films are easier and cheaper in production, and therefore more competitive in comparison with other materials used to fabricate flexible and transparent electronics devices [11,12].…”

“…CNTbased films are synthesized mainly with randomly oriented CNTs [6][7][8][9][10], but the technology for obtaining thin films with well-ordered parallel CNTs has been developed in recent years [14,15]. Highly conductive metallic CNT films with 40-70% optical transmittance in the visible range with a film thickness of 0.1-1 µm are already used [2]. Using long CNTs (∼10 µm), Mirri et al produced uniform films with a sheet resistance of ∼100 Ω/sq at ∼90% transmittance in the visible wavelength range by scalable dip-coating [6].…”

Macroscopic Freestanding Nanosheets with Exceptionally High Modulus

“…Macroscopic multifunctional nanosheets show considerable promise for a broad range of potential applications, from electronic devices − and mesoporous membranes to battery electrodes and specialty coatings for biomedical applications . They are also critical to applications in flexible electronics. − Thin films and freestanding nanosheets assembled from single-wall carbon nanotubes (SWCNTs), in particular, have unique potential utility for a wide array of applications related to flexible electronics, sensors, and solar energy conversion, − ,− but there are a number of intriguing unresolved questions related to such things as the nature of the interaction potential between colloidal SWCNTs, , the optimization of SWCNT solubility in common fluids and solvents, , the complexity of SWCNT suspension rheology , and self-assembly, , and the elastoplasticity of flexible SWCNT films and polymer nanocomposites. − …”
