Claim:
1. An apparatus for preparing a graphene-structured material, the apparatus comprising: a supply hopper configured to supply graphite oxide; a supply line of which an end is connected to a lower end of the supply hopper; a reducing atmosphere gas supply unit connected to a side of the supply line; a vertical fluidized bed furnace of which a lower part is connected to another end of the supply line and configured to reduce the supplied graphite oxide with thermal-expansion; a discharge line of which an end is connected to an upper part of the vertical fluidized bed furnace; a vertical micro filter connected to an opening portion on a side of the discharge line; a vibrator and a vacuum pump connected to the vertical micro filter; and a collector positioned under the vertical micro filter and connected to another end of the discharge line, wherein the graphene-structured material is discharged through the discharge line from the vertical fluidized bed furnace, collected at the vertical micro filter, and dropped into the collector from a vibration on the vertical micro filter created by the vibrator.
