Title:
METHOD FOR PRODUCING ELECTRICALLY CONDUCTIVE FIBER MATERIAL
Document Type and Number:
Japanese Patent JP2009084746
Kind Code:
A
Abstract:

To provide a method for producing an electrically conductive fiber material, which is capable of forming many carbon nanofibers 20 in a short time, where the carbon nanofibers exhibits desired performances in accordance with applications.

The method for producing carbon nanofibers 20 as the electrically conductive fiber material in a fibrous or tubular form includes film-forming an electrically conductive catalyst layer 12 having direct electrical conductivity on the surface of a substrate 11 made of silicon, heating the electrically conductive catalyst layer 12 and introducing a mixed gas around the layer 12 under a reduced-pressure atmosphere to generate a plasma so as to conduct a CVD (chemical vapor deposition).
