Document Type and Number:
WIPO Patent Application WO/2011/089754
Kind Code:
A1
Abstract:
Disclosed are carbon fibers having a large surface area, high graphitization degree, small fiber diameter and reduced variability (or a nonwoven fabric formed of the carbon fibers). Also disclosed is a method for producing a carbon fiber nonwoven fabric, which comprises: a dispersion liquid preparation step in which a dispersion liquid containing a resin and pitch is prepared; an electrospinning step in which a nonwoven fabric composed of carbon fiber precursors is formed from the dispersion liquid by electrospinning; and a modification step in which the carbon fiber precursors of the nonwoven fabric obtained in the electrospinning step are modified into carbon fibers.
