▎ 摘　　要

NOVELTY - The utility model is new name is in the graphene thin film and device. Preparing graphene thin film and device comprises groove body, a feeding unit and transmission device. Groove body with containing space, and the containing space comprises solution. Feeding unit may then provide graphene solution, graphene solution form on the solution surface, and graphite solution is in solution form surface graphene film, for workpiece is at least partially merged solution. When when workpiece by graphene thin film and surface of solution, graphene film is attached to on surface and processing part. So, this utility new model is convenient mass production has directional the graphene product.
