▎ 摘　　要

NOVELTY - Coating non-conductive polymer particles with graphene nanoflakes involves transferring polymer particles to a bed (203), electrically grounding the bed, transferring graphene nanoflakes to a spray nozzle, charging the spray nozzle to a high voltage to induce an electrostatic charge in the graphene nanoflakes, transferring the electrostatically charged graphene nanoflakes from the spray nozzle to the bed, and tumbling the polymer particles while the electrostatically charged nanoflakes are transferred from the spray nozzle to the bed. USE - Coating non-conductive polymer particles with graphene nanoflakes used for production of graphene coated materials (claimed) used for manufacturing mill jars and vessels. ADVANTAGE - The method is suitable for large scale production of graphene coated materials. The use of surfactants in the method eliminates or reduces clamping of the end products. The introduction of charges into graphene nanoflakes prevents restacking of graphene with non-conductive polymers. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrospray system for producing graphene nanoflakes/polymer compounds.
