Abstract
The present invention relates to a method for producing a film-type carbon material, wherein said material is made of plate-like graphite crystallites or carbon nanotubes which are deposited from a carbon-containing gaseous phase using an electric discharge. The material thus obtained can essentially be used in the production of field emitters or electrodes for electrochemical devices.
