<P>PROBLEM TO BE SOLVED: To provide highly functional graphite carbon nanofibers having high stability in size, shape, structure and purity. <P>SOLUTION: Graphite nano-carbon fibers are obtained by using an apparatus including: a reaction container 1, the inside of which can be maintained in a reducing atmosphere; a metal substrate 2 as a catalyst disposed in the reaction container; a heater 6 for heating the metal substrate; hydrocarbon supply means 5 for supplying a hydrocarbon into the reaction container; scraping means 4 for scraping carbon fibers produced on the metal substrate; a collection container 7 for collecting the scraped carbon fibers; and exhaust means 8 for exhausting gas in the reaction container. The carbon fibers are linear fine carbon fibers each having a diameter of 80-470 nm and including graphene formed so as to be stacked in multiple layers in a longitudinal direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
