▎ 摘 要
NOVELTY - Ionic liquid or aqueous phase having solubility is non-covalently bonded to electroconductive graphene and hydrophilic modified, to obtain aqueous dispersion of electroconductive graphene or dispersed slurry containing water-dispersible solid phase. USE - Preparation of aqueous dispersion of electroconductive graphene or dispersed slurry containing water-dispersible solid phase used for chemical sensor, biosensor, energy storage device, and applied catalysis and analytical application (all claimed). ADVANTAGE - The method enables preparation of aqueous dispersion of electroconductive graphene or dispersed slurry containing water-dispersible solid phase having excellent dispersibility and solubility in hydrophilic solvent.
