Eindhoven, Netherlands -- Researchers at Eindhoven University of Technology have developed a replacement for indium tin oxide (ITO). ITO is a clear, transparent, electrically-conductive substance widely used in the manufacture of touch-sensitive display screens.
The replacement material is a transparent, conducting film produced in water, and based on electrically conducting carbon nanotubes and plastic nanoparticles. It is made of commonly available materials, and on top of that is also environment-friendly.
The research team has been able to achieve higher conductivity by combining low concentrations of carbon nanotubes and conducting latex in a low-cost polystyrene film. The latex is not based on rubber, but a solution of polymer beads in water).
The results, which also provide new insights into conduction in complex composite materials, were published online on 10 April by the scientific journal Nature Nanotechnology.
