Could carbon nanotubes finally become widespread?

15/01/2013

What if I told you there is a material that is 100 times stronger than steel, weighs one sixth of that weight, and actually has better electrical and heat conductive properties? What if I told you it’s non-metallic, more robust than carbon fiber, and flexible? And what if I told you it looks like black cotton thread, because it is spun to look like fabric?

The answer is fairly simple. You would call me mad, and tell me that I’ve been reading too much science fiction lately. However, you would be wrong, because this material exists, is made of the ever elusive carbon nanotubes, and moreover, it’s partially Dutch.This material is the result of 10 years of research and development by Dutch company Teijin Aramid (based in Arnhem), in conjunction with a team of scientists from Rice University, the Air Force Research Laboratory (both institutions from the United States) and the Technion-Israel Institute of Technology. The team was successful in devising a chemical process to dissolve clumps of nanotubes in order to be able to spin them into macroscopic threads. The high tensile strength comes from the individual strands being all aligned in the same direction. This new process eliminates the brittleness commonly encountered in graphite-based fibers.The application span of this new material is virtually endless. Almost all low-power and data transfers systems and components from the aerospace, automotive, medical and, more specifically, the smart-clothing industry, can benefit from the liberties this material presents due to its flexibility and lower weight ratio. Perhaps we will finally see flexible consumer electronics and embedded technology in clothing this decade. The future is not only now, it is also flexible.
