▎ 摘 要
NOVELTY - Manufacture of graphene balls involves preparing a dispersion comprising graphene oxide, a monosaccharide to polysaccharide reducing agent and 1-10 wt.% aqueous ammonia with concentration of 25-30%, spray-drying the dispersion, and obtaining graphene balls having sphericity which is a ratio of longest diameter of graphene balls with respect to shortest diameter of graphene balls of 1-1.5. USE - Manufacture of graphene balls (claimed). ADVANTAGE - The method enables manufacture of graphene balls having uniform size, spherical shape and excellent physical and chemical properties.
