Disclosed are an iron-carbon composite in which 10 to 90% of the internal space of a nanoflake carbon tube or a nested multi-walled carbon nanotube is filled with iron carbide or iron; a carbonaceous material containing such iron-carbon composites; and a process for preparing the same. The iron-carbon composite is useful for electron emitting materials and other applications.
La présente invention concerne un composite fer/carbone comprenant: un tube de carbone en nanopaillette ou un nanotube de carbone multicouche d'une structure d'imbrication, et du carbure de fer ou du fer dans lequel 10 % à 90 % du volume intérieur du tube est comblé. Ce composite fer/carbone convient comme matériau à émission d'électrons ou dans d'autres applications.
