FORMATION METHOD OF GRAPHENE LAYER

摘要

PROBLEM TO BE SOLVED: To solve a conventional problem by providing a classification method of graphene, with which graphene can be directly aligned on a targeted substrate while classifying graphene.SOLUTION: A formation method of a graphene layer is used, which includes: a floating step to float graphene and graphite in a solvent; a magnetic field application step to apply a magnetic field to the solvent so that graphene and graphite are distributed in the solvent; a centrifugal force application step to apply centrifugal force to the solvent so that graphene and graphite are distributed in the solvent; a separation step to separate graphene from the solvent; and an application step to apply the solvent separated in the separation step and including separated graphene to a base material and to remove the solvent.
