GRAPHENE SOLUTIONS WITH HIGH COLLOIDAL STABILITY, CONDUCTIVE FILM, ENERGY STORAGE DEVICES AND SENSOR COMPRISING FILM PREPARED BY THE GRAPHENE SOLUTION, AND COATING COMPOSITION FOR RESISTING CORROSION COMPRISING THE GRAPHENE SOLUTIONS

摘要

The present invention relates to a graphene solution and, more specifically, to a graphene solution with high colloidal stability, a conductive film, an energy storage device, and a sensor formed by a graphene solution, and a coating composition for preventing corrosion comprising the graphene solution as an active component. The graphene solution comprises 0.01-30 wt% of a conductive polymer and a dopant, 0.005-40 wt% of monolayer graphene, and the remainder of a solvent. Provided is a graphene solution preventing restacking of graphene, thereby having excellent colloidal dispersibility and stability.
