▎ 摘　　要

NOVELTY - The preparation method of vertically oriented graphene-based material involves dispersing graphene-based raw material in solvent to obtain graphene dispersion liquid, filtering graphene dispersion liquid to obtain graphene film, freezing and drying graphene film. USE - The method is useful for preparing vertically oriented graphene-based material (claimed). ADVANTAGE - The method enables simple preparation of vertically oriented graphene-based material with excellent surface conductivity.
