Abstract
In this work, a comparison between the electro-optical characteristics of CNT random networks obtained through inkjet printing and spray-deposition on flexible substrates is presented. Transmittance values are similar in both fabrication techniques; however, the sheet resistance of the inkjetted layers diverges significantly with respect to the reference spray-deposited thin film. To overcome this limitation, we show a relationship between the printing resolution and the sheet resistance. Furthermore, big differences between the two studied substrates are found in the electro-optical characteristics of CNT films. This work shows a reliable procedure for the choice of substrates and printing parameters for the realization of fully inkjet-printed large area CNT networks for electrode and sensing applications.
