▎ 摘  要

NOVELTY - Producing an electrical graphene conductor comprises (i) providing a filter designed as a surface filter, (ii) providing a graphene dispersion (6) made of graphene flakes and/or graphene oxide flakes, and a dispersant (7), (iii) filtering the graphene dispersion on the filter, the graphene platelets and/or graphene oxide platelets remaining on the filter as filter cakes (8), without penetrating the filter belt (4), where the dispersant partially gets through the filter, (iv) drying the filter cake so that a graphene film (1) for use as an electrical graphene conductor is created from the filter cake, (v) designing the filter as a movable filter belt which can be driven by a conveyor i.e. runs between two rollers of the conveyor, and (vi) filtering and drying simultaneously at different points on the filter belt in a filter station or in a drying station. USE - The electrical graphene conductor is useful for electrical winding of electrical machine (claimed). ADVANTAGE - The electrical machine has a very light electrical winding having textile behavior to ease manufacture and assembly, and optimizes the power density. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the production of electrical graphene conductor. Graphene film (1) Filter belt (4) Graphene dispersion (6) Dispersant (7) Filter cake (8)
