Abstract
The present invention relates to a method for preparing graphene which comprises subjecting expanded graphite to high speed homogenization to prepare a feed solution and then subjecting the same to high pressure homogenization, thereby increasing the degree of dispersion of expanded graphite in the feed solution and so improving the efficiency of high pressure homogenization. Therefore, the present method has features that the efficiency of graphene preparation is excellent and the size of graphene to be prepared is uniform, compared with a conventional process.
