▎ 摘　　要

NOVELTY - Graphene oxide film production system comprises a feeding unit (100), an extrusion coating unit, a drying unit and a receiving unit. The coating substrate is output by the feeding unit and passes via extrusion coating unit in turn. The drying unit is rolled in the receiving unit. The extrusion coating unit comprises a coating roller (1) and a groove (3). A doctor blade (2) is arranged adjacent to the coating roller. An extrusion die (4) is provided at the feeding inlet. The coating roller is tensioned and connected with the coating substrate. The coating roller is adjacently provided with a scraper. The coating side of the scraper and the coating substrate form a coating gap. The groove has a feeding port and a discharging port. The coating side of the discharging port and the coating substrate is correspondingly set. The feeding port is provided with an extruding die head. The extruding die head is capable of extruding the graphene oxide slurry into the groove. USE - Used as graphene oxide film production system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene oxide film production system. Coating roller (1) Doctor blade (2) Groove (3) Extrusion die (4) Feeding unit (100)
