▎ 摘　　要

NOVELTY - A carbon fiber product comprises a coaxial stacking morphology of truncated conical tubular graphene layers which include stacked hexagonal carbon layers (10). Each of truncated graphene layer has large and small ring ends. The hexagonal carbon layers have exposed edges at the large ring ends. USE - The carbon product is used as material for composite, conductive resin, or ink (claimed), paints, concrete, or plating solution. The composites include conductive rubbers, cushion materials or buffers such as rubber pads, or tires. ADVANTAGE - The carbon fiber product has high degree of edge and surface activity and exhibits excellent adhesion to base material, such as resin. It has excellent dispersibility in resins and exhibits good moldability. It provides abrasion resistance, high friction force, and superior grip characteristics to tires incorporating it. It also increases conductivity of plating solution. It provides inks or paints having excellent glossiness or coloring characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for: (1) a composite comprising base material and the carbon fiber product; (2) a carbon fiber product with catalytic metal supported on the exposed part of the edges of the hexagonal carbon layers; (3) ink containing carbon fiber product; and (4) a method of adjusting the length of the above carbon fiber product by grinding in a ground ball mill. DESCRIPTION OF DRAWING(S) - The figure is a schematic view of carbon fiber having a herringbone structure. Carbon layers (10) Deposited film (12) Hole (14)
