▎ 摘　　要

NOVELTY - Preparing modified graphene aerogel comprises adding 1 pts. wt. hummers graphene oxide to de-ionized water at room temperature by ultrasonic dispersion to prepare an aqueous dispersion with a concentration of 1-10 mg/ml, adding 0.001-0.5 pts. wt. double-ended epoxy base polyether, stirring, adding 0.5-3 pts. wt. polyamine reducing agent, stirring for 0.5-2 hours, sealing and placing in a 90-120 degrees C environment and heating for 6-12 hours to obtain modified graphene hydrogel, after dialyzing modified graphene hydrogel, freeze-drying or supercritical carbon dioxide drying to obtain a modified graphene aerogel. USE - The preparing modified graphene aerogel is useful in modification of polymer material (claimed). ADVANTAGE - The method: improves compatibility of graphene aerogel and polymer materials of different polarities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for modified graphene aerogel.
