▎ 摘　　要

NOVELTY - Porous graphene framework material comprises graphene sheet layer and a poly aminopolyether amine molecular chain inter-layer linking adjacent sheets and a microporous/mesoporous pore, where mass ratio of graphene sheet and polyaminopolyetheramine is 100:10-500, and size of microporous/mesoporous pores is 0.5-50 nanometer. USE - Porous graphene framework material in biological detection, chemical catalysis, electrochemical energy storage, gas storage, gas separation, wastewater treatment, environmental protection or nano reactor (claimed). ADVANTAGE - The porous graphene framework material has adjustable pore size range of microporous/mesoporous channels. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing porous graphene frame material, which involves: (A) adding a polyaminopolyetheramine to the graphene oxide solution, and mixing uniformly at 25-150 degrees C for 2-72 hours under a heating condition to obtain a mixed suspension, where mass ratio of the polyaminopolyetheramine and graphene oxide is (0.150):1; (B) subjecting obtained mixed suspension in liquid to filtration-washing to remove unreacted free polyaminopolyetheramine to obtain a wet porous graphene frame material; and (C) spray-drying obtained wet porous graphene frame material, freeze-drying, super zero boundary drying or vacuum drying or a combination to obtain desired product.
