ULTRAHIGH GRAPHITIZATION DEGREE CARBON NANOFIBER HAVING MANY CARBON HEXAGONAL EDGE FACES ON SURFACE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ultrahigh graphitization degree carbon nanofiber having many carbon hexagonal edge faces on the surface.;SOLUTION: In the carbon nanofiber 1 constituted by further laminating along a fiber axis direction L a plurality of the carbon nano-fibril groups 4 which is obtained by laminating along a fiber axis direction L the carbon nano-fibril 3 consisting of a laminated body of the carbon hexagonal network plane so that at least one edge of the carbon hexagonal network plane 2 may form a side peripheral face of the carbon nanofiber 1, a spacing d₀₀₂ of a carbon hexagonal network plane 2 constituting the carbon nano-fibril 3 and a size Lc₀₀₂ of a laminated layer are ≤0.3360 nm and ≥20 nm respectively and also a specific surface area is ≥50 m²/g.;COPYRIGHT: (C)2006,JPO&NCIPI
