| Abstract Scope |
Additive printing of electronics directly onto any surface has been sought for decades. Despite significant progress, reports on fully direct-write printed electronics continue to rely on excessive thermal treatments and/or fabrication processes external from the printer. In this keynote, recent progress towards print-in-place electronics will be discussed; print-in-place involves loading a substrate into a printer, printing all needed layers, then removing the substrate with electronic devices immediately ready to test. Inks from various nanomaterials make this possible, including 2D graphene and hexagonal boron nitride, and 1D carbon nanotubes. Using an aerosol jet printer, these nanomaterial-based inks are printed into thin-film transistors (TFTs) using a maximum process temperature of 70 ºC. Complete recyclability of these print-in-place transistors will be discussed, fabricated entirely using nanoscale carbon-based inks. Finally, the same set of carbon-based inks will be demonstrated for use in all-aqueous (completely water-based) printed CNT-TFTs, eliminating dependence on processing with hazardous chemicals. |
