Desktop printer creates carbon nanotube ink
Researchers at Rensselaer Polytechnic Institute have used a conventional desktop printer to print patterns of carbon nanotubes, according to a Rensselaer press release:
Using an off-the-shelf inkjet printer, a team of scientists has developed a simple technique for printing patterns of carbon nanotubes on paper and plastic surfaces. The method, which is described in the August 2006 issue of the journal Small, could lead to a new process for manufacturing a wide range of nanotube-based devices, from flexible electronics and conducting fabrics to sensors for detecting chemical agents.
Carbon nanotubes have enticed researchers since their discovery in 1991, offering an impressive combination of high strength, low weight, and excellent conductivity. But most current techniques to make nanotube-based devices require complex and expensive equipment.
"Our results suggest new alternatives for fabricating nanotube patterns by simply printing the dissolved particles on paper or plastic surfaces," said Robert Vajtai, a researcher with the Rensselaer Nanotechnology Center at Rensselaer Polytechnic Institute and corresponding author of the paper.
Although the applications and implications aren't yet clear, this could be a big step forward in the commercialization of some of carbon nanotubes' powerful properties. (photo University of Oulu/K. Kordas and G. Toth)
