Development of Transparent Conductive Single-Walled Carbon Nanotubes Films

Abstract

In our research, we aim to formulate SWNTs ink and develop a methodology to create enhanced conductive flexible transparent SWNTs films that have the potential to possibly reduce the use of ITO. In our preliminary findings, we achieved a sheet resistance of 25.1 kΩ/sq with ∼93% transparency (excluding film) by spraying a unsorted purified pristine SWNTs. In-house separated M-SWNTs, prepared using agarose gel separation methods, were sprayed with sheet resistance of 3.3 kΩ/sq and ∼86% transparent.. Investigation of tube length with respect to conductivity was also studied — nanotubes were sonicated for different durations (thus affecting tube length) before separation and spraying.
