NOVELTY - Manufacture of graphene involves absorbing a strong acid into graphite to form slurry, adding an aqueous solution of potassium permanganate to slurry, stirring, peeling the resultant product, and reducing. USE - Manufacture of graphene (claimed). ADVANTAGE - The method enables manufacture of graphene having improved interlayer spacing, with reduced usage amount of strong acid.
