▎ 摘　　要

NOVELTY - Micro-fluidic reaction system, comprises multiple raw material tanks, a micro-channel reactor, a filtering device and multiple collecting tanks. A part of the raw material tank is used for storing the graphene dispersion liquid, and the other part of the raw material tank is used for storing the reduced agent solution. The micro-channel reactor is used for inputting the graphene dispersion liquid and reducing the agent solution to mix and react. The filtering device is used for separating the solvent containing reduction agent reduction oxidation graphene the product. The part of the collecting tank is used for collecting the filter cake of the reduction graphene filter cake, and the other part of the collecting tank is used for collecting the mixed solution filtered by the filter device. USE - Used as micro-fluidic reaction system. ADVANTAGE - The micro-fluidic reaction system reduces the reaction facility occupied space, continuous preparation reducing and oxidizing graphene, and reduces the pressure drop and the reduced reaction flux for preparation operation and scale. The channel size is too large to prolong the mass transfer path of the reaction species in the channel to reduce the mixing ability, so it is necessary to select proper reactor size. The liquid holding amount of single micro-channel reactor is 1.57 or 2.36 ml, by changing the microchannel reactor number adjusting reaction processing amount. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing reducing graphene oxide using micro-fluidic reaction system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the microfluidic reaction system. 1First raw material tank 2Second raw material tank 3First feeding pump 4Second feeding pump 5Micro-channel reactor 6Filtering device 7First collecting tank 8Second collecting tank
