NOVELTY - Apparatus (A1) comprises: (a) a chamber (110) which has a through-hole formed at its one surface; (b) a cylinder (120) which receives graphite and a volatile material to be vaporized at room temperature and has an opening to be corresponding to through-hole of chamber, and which is disposed at an outside of chamber; (c) a clamp (130) which is disposed in chamber to pass through through-hole of chamber and thus selectively seal the opening of cylinder; and (d) an operation mechanism which is connected with clamp and moves clamp so that the opening of cylinder is selectively sealed by clamp. USE - The apparatus is useful for exfoliation of graphene or manufacturing graphene (claimed). ADVANTAGE - The apparatus: simplifies the manufacturing process of graphene and reduces the manufacturing cost; and provides graphene without utilizing sulfuric acid, and without performing thermal treatment process at a high temperature, thus preventing the properties of graphene from being deteriorated. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an apparatus for exfoliation of graphene, comprising (a) as above per se, a cylinder which receives graphite and a material having a boiling point of less than or equal to 200 degrees C and has an opening to be corresponding to the through-hole of the chamber, and which is disposed at an outside of the chamber, (c) and (d) as above per se, and a heating unit which heats the cylinder; (2) method for exfoliation of graphene, comprises filling graphite and a volatile material to be vaporized at room temperature in a cylinder, and installing the cylinder at a chamber sealing the cylinder by moving a clamp, and moving the clamp and releasing an internal pressure of the cylinder when the internal pressure of the cylinder is more than a predetermined value due to vaporization of the volatile material; and (3) a graphene manufactured by the method. DESCRIPTION OF DRAWING(S) - The figure shows a cross-sectional view of the apparatus. Chamber (110) Cylinder (120) Clamp (130) Operation lever (140) Link member (150)
