▎ 摘　　要

NOVELTY - Manufacture of graphene dispersion liquid involves immersing graphite rod into an aqueous solution of a triazine derivative by applying pulse plasma (6). USE - Manufacture of graphene dispersion liquid used for preparing graphene (claimed) for use in electrode materials of fuel cell, supercapacitor and dye-sensitized solar cell. ADVANTAGE - The method enables economical manufacture of graphene using dispersion liquid with high dispersion stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene, which involves removing triazine derivative from graphene dispersion liquid, filtering the liquid, and preparing a solid-state graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an apparatus for manufacturing graphene dispersion liquid.
