▎ 摘　　要

NOVELTY - Preparing graphene aerogel comprises (i) adding reducing agent into the graphene oxide dispersion liquid to obtain the graphene oxide printing slurry, where the mass ratio of the reducing agent and the graphene oxide is 1:4-4:1; (ii) using the graphene oxide printing slurry by 3-D printing, obtaining ordered three-dimensional graphene oxide porous bracket; (iii) placing the three-dimensional graphene oxide-based porous bracket in water vapor atmosphere for 10-25 hours so that the graphene oxide is reduced and self-assembled to obtain the graphene hydrogel; and (iv) freezing and drying the obtained graphene hydrogel to obtain graphene aerogel. USE - The method is useful for preparing macrostructure ordered graphene gas gel. ADVANTAGE - The method enables to prepare macroscopic ordered graphene aerogel in simple manner.
