AIST: Carbon nanotube · High conductivity / coating film developed – IoT device electrode material

point

  1. No need for aftertreatment steps such as removal of dispersant and doping after film formation, allowing for universal film thickness control
  2. Excellent resistance to high temperature and high humidity environment, flexibility and elasticity, adaptable to various substrates and various film formation technologies
  3. It achieves 20,000 S / cm which is comparable to metal particles and is expected for a wide range of applications such as printed electronics

Indium tin oxide (ITO) films are currently mainly used as materials for transparent electrodes such as displays, touch panels, and solar cells

Since it is difficult to deal with expansion and contraction and folding required for members of future IoT devices, development toward practical application of new materials to replace ITO is being vigorously pursued.
