Could carbon nanotubes be part of the solution which finally brings us roll-up displays?
The researchers discovered that if they took boron-doped carbon nanotubes, which provide good electrical and mechanical properties, and placed them on a transparent substrate, the result was a flexible electrical pathway that can be used to create electrodes. The researchers have used these electrodes to create a flexible light-emitting device. Both the anode and cathode are transparent which, even when repeatedly bent, twisted, rolled or folded completely over, continue to conduct electricity without losing any notable properties. The electrical pathways are created by uniformly dispersing carbon nanotubes in a homogeneous 20nm thin film layer of an undisclosed polymer solution sitting atop a thin sheet of transparent polyethylene terephthalate (PET). A process called spin coating is used to deposit the carbon nanotubes into/onto the polymer. After creating the material it is allowed to cure. Researchers began testing its electrical properties and very quickly discovered that the flex
