Flexible, Stretchable, Transparent Conducting Films Made from Superaligned Carbon Nanotubes

Abstract

A straightforward roll‐to‐roll process for fabricating flexible and stretchable superaligned carbon nanotube films as transparent conducting films is demonstrated. Practical touch panels assembled by using these carbon nanotube conducting films are superior in flexibility and wearability—and comparable in linearity—to touch panels based on indium tin oxide (ITO) films. After suitable laser trimming and deposition of Ni and Au metal, the carbon nanotube film possesses excellent performance with two typical values of sheet resistances and transmittances (208 Ω □−1, 90% and 24 Ω □−1, 83.4%), which are comparable to ITO films and better than the present carbon nanotube conducting films in literature. The results provide a route to produce transparent conducting films more easily, effectively, and cheaply, an important step for realizing industrial‐scale applications of carbon nanotubes for transparent conducting films.

Development of a Novel Bidimensional Spectroelectrochemistry Cell Using Transfer Single-Walled Carbon Nanotubes Films as Optically Transparent Electrodes

“…Meanwhile, homogeneous thin films of CNTs are required for several applications, 17 highlighting sensors 18 and OTEs. [19][20][21][22][23] The transference of CNTs films to a variety of supports is of great importance. This transference step is commonly carried out with chemical vapor deposition (CVD) films 24,25 using different methods including dry-transfer, 26 imprinted conductive adhesive, 27 functionalization of CNTs, 28 transfer printing, 29 contact printing, 30 stacked multiple transfer, 31 spin coating of a polymethylmethacrylate film, 32 using the growth substrate as a stamp, 33 one-step direct transfer, 34 laser assisted, 35 or using polydimethylsiloxane.…”

Modification of Spray-Method for Producing of Single-Walled Carbon Nanotubes Films and Their Properties

“…Однослойные углеродные нанотрубки (ОУНТ) интенсивно исследуются для их дальнейшего применения в электронике [6]. Одной из возможных областей, где ОУНТ могут раскрыть свой потенциал, признано изготовление оптически прозрачных проводящих пленок [7][8][9]. В отличие от оксидных прозрачных электродов нанотрубные обладают высокой гибкостью и прозрачностью в ИК-диапазоне.…”
