ADVANTAGE - The device is capable of economically preparing the graphene with good electrical property and chemical property. DETAILED DESCRIPTION - The device comprises has a chamber, a material inlet and an exhaust outlet, where gaseous carbon source is placed into the chamber with a slit. A winding unit is arranged in a locking position. A fixing unit is connected to an inner part of the chamber to discharge the carbon source. An open space portion of the chamber is provided with a fixed graphite catalyst. A carbon fiber heating unit is connected with an extraction unit. The chamber is provided with a vacuum pump and a gate chamber. A winding roller is connected with a fixing plate for rotating and dissolving graphite catalyst in the winding roller, where the graphite catalyst is transferred to a transferring roller. The transferring roller includes a power transmission element connected with the fixing plate. The winding roller is connected with the fixing plate and the power transmission element. A rotary plate is connected with the fixing plate. The power transmission element delivers power to a rotating unit, which rotates the winding roller, the recovery roller and transferring roller using a motor. The heating unit emits laser beam for heating a materials in a heating zone. The heating unit is provided with a power source and a heating assembly. An INDEPENDENT CLAIM is included for a method for preparing a graphene.
