GRAPHENE SHEET AQUEOUS DISPERSION, METHOD FOR PRODUCING THE SAME, AND GRAPHENE-CONTAINING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide: an inexpesively-preparable graphene sheet aqueous dispersion capable of dispersing a graphene sheet in high concentration stably by suppressing aggregation of each graphene; a method for producing the same; a graphene oxide aqueous dispersion used as a raw material for producing the graphene sheet; and a graphene-containing structure obtained by removing an aqueous solvent from the graphene sheet aqueous dispersion.;SOLUTION: A graphene sheet aqueous dispersion includes a water-soluble compound having a 9,9-bis (substituted aryl) fluorene skeleton, a graphene sheet and an aqueous solvent. The graphene sheet aqueous dispersion is obtained by, for example, preparing a graphene oxide aqueous dispersion containing a water-soluble compound having a 9,9-bis (substituted aryl) fluorene skeleton, graphene oxide and an aqueous solvent, and then applying a reduction treatment thereto.;COPYRIGHT: (C)2014,JPO&INPIT
