R2R Printed Carbon Nanotube TFT Sheets

This presentation covers our progress in high purity 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 (isolation of high purity sc-SWCNT), with special consideration given to the effects of solvent parameters and doping on the yield/purity of the final product. Fully printed transistors combining R2R gravure and inkjet-printing will be described as well as our recent progress in realizing “limitless” R2R gravure printed TFT backplanes capable of driving an e-paper display.

Bio

Dr. Patrick Malenfant studied chemistry at the University of Ottawa (BSc 1995), Cornell University (MSc 1997), and the University of California - Berkeley (PhD 2000). He has 10 years of industrial R&D experience including a one year postdoc at IBM's TJ Watson Research Center and 9 years at the GE Global Research Center where he developed nanomaterials for Aerospace, Healthcare, and Organic Electronics applications. He joined the National Research Council of Canada in 2010 as a Senior Research Officer. He is currently the Director of R&D in the Security and Disruptive Technologies Research Center overseeing activities in Quantum Science, Printed Electronics and Structural Materials.
