Carbon Nanotube Polymer Nanocomposites For Field Emission Cathodes

Scientists have discovered that you can produce a composite of carbon nanotubes embedded in a polymer that gives outstanding performance as an electron emitter material. Under high voltage these electrons strike a phosphor screen producing the familiar colours of red, green and blue and opens up the possibility of highly efficient large area field emission displays as well as possible uses as low power back lighting units in LCD televisions.
