Black single-walled carbon nanotubes SWCNT for transparent conductive films

Transparent conductive films (TCFs) are important components of a variety of electronic and optoelectronic devices, such as touch screens, smart windows, liquid crystal displays, organic light-emitting diodes, and organic photovoltaic cells. Single-walled carbon nanotubes are considered to be ideal candidates for new transparent conductive materials due to their excellent optical, electrical, and mechanical properties, such as good conductivity, high structural stability, high flexibility, low refractive index, and low haze.

Single-walled carbon nanotube transparent conductive films are expected to replace indium tin oxide as a new generation of transparent conductive films due to their high transparent conductivity and flexibility. Researchers used the characteristics of SWCNTs, which are spontaneously dispersed, additive-free, and have high structural integrity, to prepare single-walled carbon nanotube transparent conductive films with transmittances of 82% and 90% and surface resistances of 133Ω·sq-76, respectively. The application of single-walled carbon nanotubes in the field of transparent conductive films has laid a foundation and is of great significance for promoting the development of flexible electronic products.
