| Summary: | Carbon nanotubes (CNTs) and graphene have shown promising potential as
next-generation transparent conducting materials due to their high electrical and
thermal conductance, flexibility and transparency in both visible and infrared spectral
regions. In this study transparent and conductive thin films with a novel
hemicellulose and double-walled carbon nanotube (HC-DWCNT) hybrid material
were produced with spray-coating, droplet casting and vacuum filtration deposition
methods. HC-DWCNT material is easily dispersed in water and usable for
mass-production. These films showed good conductivity, stability at ambient air,
very good transparency in the visible and excellent transparency in the infrared
spectral regions while having few percent haze. The best sample had sheet resistance
of 115 ± 9 ohm/sq and direct transmittance of 81.6 % at 550 nm wavelength.
The properties of the prepared films were compared to CNT, graphene and their
hybrid films reported by research groups by reviewing their fabrication methods
and film performances. While many of these other films have shown higher shortterm
quality, it was found that the performances of HC-DWCNT films were quite
promising for future development considering the stability of the films and the fact
that dopants or post-treatments were not used for enhancing the performance of
the best samples.
