METHOD AND APPARATUS FOR PREPARING HIGH-QUALITY GRAPHENE USING SHEAR FLOW

摘要

Disclosed is a method and apparatus for preparing high-quality graphene using shear flow. The method for preparing graphene according to the present invention comprises the steps of: putting a graphite-based material into a fluid containing a solvent, stored in a reaction space of a reactor; and rotating the fluid, into which the graphite-based material has been put, to perform the delamination of the graphite-based material by shear force occurring by the rotational flow of the fluid, thereby preparing graphene.
