    摘要： Graphene particulates, especially graphene nanoribbons (GNRs) and graphene quantum dots (GQDs), and a high-throughput process for the production of such particulates is provided. The graphene particulates are produced by a nanotomy process in which graphene blocks are cut from a source of graphite and then exfoliated into a plurality of graphene particulates. Graphene particulates having narrow widths, on the order of 100 nm or less, can be produced having band gap properties suitable for use in a variety of electrical applications.

    摘要： Provided is an apparatus and method for exfoliation of graphene, comprising a chamber which has a through-hole formed at one surface thereof; a cylinder which receives graphite and a volatile material to be vaporized at room temperature and has an opening to be corresponding to the through-hole of the chamber, and which is disposed at an outside of the chamber; a clamp which is disposed in the chamber to pass through the through-hole of the chamber and thus selectively seal the opening of the cylinder; and an operation mechanism which is connected with the clamp and moves the clamp so that the opening of the cylinder is selectively sealed by the clamp. Therefore, it is not necessary to use an acid like sulfuric acid, and it is also not necessary to perform a thermal treatment process for removing sulfuric acid.
