Beschreibung
Zusammenfassung:	A process for large-scale production of graphene comprising a step of applying graphene onto a movable surface carrying multiple particles using a PECVD-based process operating at low temperatures enabling the coating of materials that are at risk of melting, decomposing or deforming at higher temperatures. The graphene can be separated from said particles, and the particles re-circulated in the process. A production unit designed for continuous or semi-continuous large-scale production of graphene and graphene-coated particles, where said graphene-coated particles are either the desired end-product, or an intermediate. Graphene-coated particles, in particular particles where the graphene forms flakes having a desired orientation in relation to a surface of said particles.
