▎ 摘　　要

NOVELTY - The method involves adding natural graphite, alkali metal and aromatic compound catalyst to an organic solvent. Constant temperature reacting process is performed until system changes from black to yellow green to obtain a graphene reduction intermediate data. Carboxylate reagent is added to the graphene reducing intermediate data. Constant temperature reaction, washing, filtering and simple processing operations are performed to obtain carboxylate graphene. Natural graphite is selected as crystalline flake graphite ot block-shaped graphite. USE - Carboxyl modified graphene material manufacturing method. ADVANTAGE - The method enables reducing multiple defects of the existing graphene and prepared carboxylated graphene lattice defects and increasing conductivity. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a carboxyl modified graphene material manufacturing method. (Drawing includes non-English language text).
