▎ 摘　　要

NOVELTY - A fluorinated carbon fiber comprises a coaxial stacking morphology of truncated conical tubular graphene layers. Each layer includes a hexagonal carbon layer and has a large ring end at one end and a small ring end at the other end in an axial direction. At least part of edges of the hexagonal carbon layers is exposed at the large ring ends. The exposed edges are fluorinated. USE - The fluorinated carbon fiber is for use in an active material for battery or for use in a solid lubricant (claimed). It may also be used as water-repellent or oil-repellent agents, anti-tackiness agents, conductive agents, various types of composites, toner additives or carrier coating additives for electrostatic development, fuser rollers, phosphoric acid fuel cells, air-zinc batteries, or nickel-hydrogen batteries. ADVANTAGE - The fluorinated carbon fiber has high conductivity and excellent mechanical strength. It maintains slippage between AB planes. It has excellent lubricity when mixed with a base material, e.g., epoxy resin or oils and fats. DETAILED DESCRIPTION - A fluorinated carbon fiber comprises a coaxial stacking morphology of truncated conical tubular graphene layers. Each layer includes a hexagonal carbon layer (10) and has a large ring end at one end and a small ring end at the other end in an axial direction. At least part of edges of the hexagonal carbon layers is exposed at the large ring ends. The exposed edges of the hexagonal carbon layers are fluorinated and have a structure shown by CxFy. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of an enlarged transmission electron micrograph of a carbon fiber having a herring-bone structure manufactured by a vapor growth process.
