METHOD FOR PRODUCING CARBON FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a carbon fiber that is capable of imparting sufficient conductivity by a small amount of addition and is excellent in permeability or dispersibility into a resin or a liquid.

SOLUTION: The method for producing a carbon fiber includes: synthesizing a fibrous carbon by contacting a supported catalyst comprising a particulate carrier and a metal catalyst with a carbon element containing material; mixing the fibrous carbon having an average fiber diameter of 5-50 nm and a bent structure with boron or a boron compound; and then subjecting the mixture to a heat treatment at a temperature of 1800°C or higher.
