▎ 摘　　要

NOVELTY - Preparing graphene composite aerogel, comprises (i) adding graphene powder into potassium permanganate solution and stirring to obtain graphene oxide, drying, and then adding deionized water to obtain graphene oxide solution, (ii) mixing the silver nano-wire solution with graphene oxide solution to obtain mixed solution, (iii) mixing acetone, tin(II) chloride and polypyrrole, stirring uniformly, then adding phenolic resin, and stirring to obtain mixed solution, (iv) mixing and stirring the mixed solution of step (ii) with the mixed solution of step (iii), then heat treating in hydrothermal reactor at 80-120 degrees C for 5-9 hours, drying and cooling to obtain graphene oxide aerogel, and (v) immersing the graphene oxide aerogel prepared in step (iv) in aqueous ammonia at 0-150 degrees C, soaking for 1-36 hours, and freeze-drying to obtain final product. USE - The method is useful for preparing graphene composite aerogel. ADVANTAGE - The method: utilizes readily available raw materials; reduces production cost; is simple, harmless to the human body and the environment; and is suitable for industrial production. The graphene composite aerogel is non-toxic and tasteless.
