Future Electronics Will Be Flexible And Transparent Due To Carbon Nanotubes
Traditionally indium tin oxide (ITO) is used to make a transparent conductive coating for see-through screens, yet ceramics is rigid. Flexible screens are now made with a metal foil backing, though a metal foil is opaque. Thus to make a touchscreen flexible and transparent you need futuristic carbon nanotubes, which, as researchers from the Rice University claim, can be used to do absolutely anything. They have lately developed an innovative method to induce carbon nanotubes into a high quality thin and 90% transparent conductive sheet: the sheets are composeed of meshes of nanotubes, which are only a few nanometers thick, but that’s enough to be integrated into something like a cellphone display. This thin film for a cell phone would need a few micrograms of nanotubes, so it wouldn’t be as expensive as ITO is, and would feature similar properties in transparency and conductivity.
