Development of Functional Materials and their Integration for Application of Printable Electronics

The Printable Electronics (PE) program at the National Research Council (NRC) develops key technologies – materials, ink, printing, ICT and additive manufacturing – in order to enable a competitive and sustainable PE sector in Canada. Progress has been made over the last 15 years, yet many challenges remain at the materials, fabrication and integration level, limiting performance and commercialization. This presentation covers our semiconducting single-walled carbon nanotube (sc-SWCNT) enrichment and transistor fabrication via solution based processes. I will highlight our recent progress in understanding sc-SWCNT enrichment using conjugated polymers, challenges and advances associated with using polymer-based dielectrics and the use of conductive molecular inks. The material developments described here have enabled the realization of fully inkjet-printed transistors as well as a demonstration of a fully additive process to make thin film transistor backplanes via a roll-to-roll printing process.
