▎ 摘　　要

NOVELTY - Manufacturing graphene solution, comprises adding soluble conductive polymer solution and graphite to water or organic solvent to prepare a mixed solution, and physically decomposing the obtained mixed solution for 1-60 minutes, uniformly dispersing single-layer graphene to obtain graphene solution with high colloidal stability. Graphene is pure graphite or exfoliated graphite. The soluble conductive polymer solution is obtained by dissolving polypyrrole, polyaniline, polythiophene or its derivatives as a single conductive polymer and a dopant in water or an organic solvent. USE - The graphene solution is useful in conductive ink, single layer graphene, and for manufacturing conductive film (all claimed). ADVANTAGE - The method provides graphene solution with excellent dispersibility and high stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) the graphene solution with high colloidal stability with uniformly dispersed single-layer graphene, prepared by the above method; and (2) manufacturing conductive film, comprising coating the graphene solution on a substrate, and drying at 10-180 degrees C. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic process flow for manufacturing graphene solution (Drawing includes non-English language text).
