▎ 摘　　要

NOVELTY - A graphene solution is obtained by dissolving water or organic solvent-soluble conductive polymer, a dopant and single layer graphene in a solvent, and uniformly dispersing. The content of dopant and polymer is 0.01-30 wt.%. The content of graphene is 0.005-40 wt.%. USE - Graphene solution for conductive film used for energy storage device including super capacitor and lithium ion battery, sensor including chemical sensor for detecting toxic gases, and coating composition (all claimed). ADVANTAGE - The graphene solution has high colloidal stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) conductive film; (2) energy storage device; (3) sensor; and (4) coating composition.
