Paper Abstract

A printable high-speed flexible electronics based on ultrapure carbon nanotube (CNT) solution is reported. The carrier transport layer of the CNT-flexible electronics is formed at room temperature by dispensing a tiny droplet of an electronic-grade CNT solution that does not contain any surfactant. This CNT-TFT exhibited a high modulation speed of 312 MHz and a large current-carrying capacity beyond 20 mA. The carrier transport layer of the CNT-flexible electronics also show a high transparency of over 90% in the longwave infrared (LWIR) region. Such IR-transparent electronics are of great importance for a great variety of applications including IR-transparent smart-skins, IR-invisible antennas, and embedded IR-sensing, imaging and communications. The ink-jet printing compatible process would enable mass production of large-area electronic circuits on virtually any desired flexible substrate at low cost and high throughput.
