摘 要：Fully printable flexible transistors are key to high throughput production of flexible electronics at low cost. In this work, the advantages of an inverse gravure printing system and the solution-processing of 99% semiconductor enriched single-walled carbon nanotube (SWCNT) solutions are combined to fabricate fully printable SWCNT flexible top-gated thin-film transistors. The fully printed transistors exhibit high performance with mobility and on/off ratio up to 7.8 cm2/Vs and 104 while remaining stable when bent to 1 mm radius of curvature. With the transistors’ high performance, throughput, uniformity, flexibility and stability, we have demonstrated the potential for our printing process scheme to serve as the backplane for future scalable, low cost, high throughput, flexible electronics applications.
