▎ 摘　　要

NOVELTY - Manufacturing high concentration graphene solution involves injecting the graphene solution to the hollow fiber filter and repeating the process. The graphene of the size smaller than the diameter of the hollow fiber pore is ejected and allowed to pass through outer hollow fiber filter. The graphene solution is passed through longitudinal direction of the hollow fiber filter. USE - Method for manufacturing high concentration graphene solution (claimed). ADVANTAGE - The method enables to manufacture high concentration graphene solution in simple and quick manner that has uniform particle size distribution.
