▎ 摘　　要

NOVELTY - Preparing graphene nano-sheet/cellulose aerogel complex material comprises (1) adding graphene nano-sheets to deionized water and ultrasonically dispersing for 1-1.5 hours to obtain a graphene nano-sheet solution with a mass concentration of 1 wt.%, (2) immersing the cellulose aerogel in the graphene nano-sheet solution, ultrasonically dispersing for 5-45 minutes, and then drying in an oven to obtain the graphene nano-sheet/cellulose aerogel, (3) soaking the graphene nano-sheets/cellulose aerogel in the polyvinylidene fluoride/N'N dimethylformamide solution, solidifying, heating and pressing to obtain a graphene nanosheet/cellulose aerogel complex material. USE - The method is useful for preparing graphene nano-sheet/cellulose aerogel complex material. ADVANTAGE - The complex material has low filler content, low thickness and high electromagnetic shielding performance. The method is simple and feasible, has lower production cost, and is easy to mass production.
