▎ 摘　　要

NOVELTY - Graphene film roll-to-roll production device comprises a vacuum cavity, a vacuum pump assembly and a filling assembly, where the process gas further comprises one monitoring component and a parameter control assembly. The vacuum chamber comprises an unreeling chamber connected in turn, growth chamber and the winding chamber (13), where one of the monitoring component is connected to the growth chamber (12), to obtain a first of a graphene film in the growth chamber characterization parameter, and the first characteristic parameter and a first set of characterizing parameters are compared to obtain a first comparison result. The parameter control module is connected to the one monitoring component in response to the first comparison result, and adjusting gas quantity and proportion of each process or the temperature of growth cavity or growth substrate (7) moving speed or pressure in the growth chamber. USE - Graphene film roll-to-roll production device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing roll-to-roll graphene film, which involves (A) providing a vacuum cavity, the vacuum cavity including an unwinding cavity, a growth cavity, and a rewinding cavity; (B) providing one monitoring component, where one of the monitoring components is connected to the growth cavity to obtain a first characterization parameter of the graphene film located in the growth cavity, and comparing the first characterization parameter with a first setting the characterization parameter comparison to obtain a first comparison result; (C) providing parameter control component, connecting the parameter control component to one monitoring component, and is used to respond to the first comparison result; and (D) adjusting the flow rate and ratio of each process gas or the growth chamber temperature and the growth speed of the growth substrate or the pressure in the growth cavity, so that the first characterization parameter is equal to the first set characterization parameter. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of the graphene film roll-to-roll production device.
