The use of carbon nanotubes moves on at a pace. It is starting to look a lot closer to actual products being available using this method, maybe giving us flexible newspapers in the not too distant future – Deskarati
As part of NEDO’s Industrial Technology Research Grant Japan-Finland collaborative project, Professors Yutaka Ohno from Nagoya University in Japan and Esko I. Kauppinen from Aalto University in Finland along with their colleagues have developed a simple and fast process to manufacture high-quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate.
They used this technology to manufacture the world’s first sequential logic circuits using carbon nanotubes. The technology could lead to the development of high-speed, roll-to-roll manufacturing processes to manufacture low-cost flexible devices such as electronic paper in the future. The results were published on Feb. 6, 2011 in the online edition of the journal Nature Nanotechnology.
Lightweight and flexible devices such as mobile phones and electronic paper are gaining attention for their roles in achieving a smarter ubiquitous information society. For flexible electronics, as a substitute for conventional solid silicon substrates, there is a demand for integrated circuits to be manufactured on a plastic substrate
