<p><P>PROBLEM TO BE SOLVED: To obtain a carbonaceous minute fibrous body having excellent kneadability with a resin and excellent electroconductivity by purifying the carbonaceous minute fibrous body. <P>SOLUTION: The carbonaceous minute fibrous body is dispersed into an aggregate particulate liquid, an energy such as ultrasonic waves, etc., are applied to the dispersion from the outside, the carbonaceous minute fibrous body is separated from catalyst particles and the catalyst particles are removed. Since the catalyst particles settle by the force of gravity, the purified carbonaceous minute fibrous body is obtained by taking out the settled catalyst particles. The dried carbonaceous minute fibrous body is obtained by removing the liquid by a method such as evaporation, filtration, drying, etc., from the dispersion from which the catalyst particles are removed. When the carbonaceous minute fibrous body is used for producing a coating, ink, etc., the dispersion is supplied as it is for the production. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
