Abstract
PURPOSE: To obtain a carbon fiber having a good hydrophilic surface by attaching an alkali metal salt or ammonium salt of humic acid on the surface of the carbon fiber. CONSTITUTION: This hydrophilic carbon fiber is obtained by carrying out a dipping treatment of a carbon fiber in 0.1-15 wt.% aqueous solution of an alkali metal salt or ammonium salt of humic acid, separating the treated carbon fiber from the treating liquid by a filter or the like, and drying the separated carbon fiber by a vacuum drying or the like. According to the treatment, the effect same as an oxidation treatment can be provided very easily without previously applying a surface treatment such as the oxidation treatment. The treatment is effective to the carbon fiber having <=1 μm diameter and <=3 mm length, and obtained by a gas phase method (the fiber easily damaged by the oxidation) in the carbon fibers.
