METHOD FOR FABRICATING DRY/WET GRAPHENE FLAKES AND GRAPHENE FLAKES FABRICATED THEREBY

WIPO Patent Application WO/2022/065839

A1

The present invention relates to: a method for fabricating graphene flakes from graphite by using a physical method; and graphene flakes fabricated thereby. The method for fabricating graphene flakes, according to the present invention, involves simple processes and enables graphene flakes to be obtained from graphite with high yield within a short period of time. Also, graphene flakes fabricated thereby have high purity and uniform particle characteristics, and thus are very excellent in industrial application.
