摘要： The present invention relates to a method and apparatus for producing a nanoscale material having a graphene structure. The present invention provides a method and apparatus which compulsorily introduces graphite sulfuric acid slurry and a permanganate sulfuric acid solution into a microchannel, to cause an oxidation reaction among layers of graphite, and which in particular involves applying ultrasonic waves during the reaction in the microchannel to improve expansion and delamination efficiency among layers of graphite, injecting an aqueous hydrogen peroxide solution into a reaction termination portion to terminate the oxidation reaction, and cleaning and drying the thus-obtained reaction mixture to produce graphite oxide. The present invention also provides a method and apparatus which involve supplying the thus-produced graphite oxide into a fluidized bed furnace to produce a nanoscale material having a graphene structure through delamination caused by thermal shock. According to the present invention, the risk of explosion is reduced during the production of graphite oxide, mass production of graphite oxide is enabled, and a nanoscale material having a graphene structure, physical properties equal to those of carbon nanotubes, and superior dispersibility is produced.

摘要： The present invention is directed to a method of producing nano-size graphene-based material and an equipment for producing the same. The present invention provides a method of producing graphitic oxide by forcing graphite sulfuric slurry and KMnO 4 sulfuric solution into a lengthy micro-channel and by sustaining the mixture of the said graphite sulfuric slurry and the said KMnO 4 sulfuric solution in the said micro-channel at predetermined temperatures, by putting the said aqua solution of hydrogen peroxide to the reaction mixture to terminate oxidation, and by washing and drying the reaction mixture. The present invention provides a method of producing nano-size graphene-based material by exfoliating graphitic oxide by thermal shock in a vertical fluidized furnace. According to the present invention, graphitic oxide can be produced massively without risks of explosion by forcing all reagents as liquid phase continuously into a lengthy micro-channel surrounded and thermally controlled strictly by heat exchangers. Nano-size graphene-based material derived by exfoliating thus produced graphitic oxide can be imported into compositions and composites for various uses since it has physical characteristics comparable to carbon nanotube and dispersibility superior to carbon nanotube via residual functional groups.
