Patent

CA 2424969

The present invention relates to fullerene carbon nanotubes having a cyclindrical wall comprising a double layer of carbon atoms (3) and methods for the production and application of them, and to nanotubes with controlled number of carbon layers and methods for production of macroscopic amounts of them and application using them, such as cold filed electron emission devices comprising light emitting CRT's.

L'invention concerne des nanotubes de carbone fullerène pourvus d'une paroi cylindrique comportant une double couche d'atomes de carbone (3), ainsi que leurs procédés de production et d'application. Elle concerne également des nanotubes dotés d'un nombre déterminé de couches de carbone, ainsi que leurs procédés de production en quantités macroscopiques et leurs applications, par exemple des dispositifs à émission de champ électronique froid comportant des tubes cathodiques électroluminescents.
