▎ 摘　　要

NOVELTY - The method involves performing the oxidation of graphite powder after expansion by electrostatic duster vibration feeding roller system (2), and pressing the graphite powder into graphite oxide film. An oxidized graphite film is divided into continuous oxidation graphite fibers using a thin film cutting machine (4) to press the same surface line speed. The graphite oxide fibers are transformed into graphene fibers. The graphene fiber is outputted to a winding device, and directly into a graphene fiber bobbin (6) with twist. USE - Electrostatic vibration powdering dry dusting preparation method of graphene fiber. ADVANTAGE - The electrostatic vibration powdering dry dusting preparation of graphene fiber is performed efficiently at low cost in simple manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the electrostatic vibration powdering dry dusting preparation method of graphene fiber.
