▎ 摘　　要

NOVELTY - Construction of graphene protective structure involves adding graphite oxide to deionized water, ultrasonically dispersing, obtaining 0.5 mg/ml to 20 mg/l graphene oxide dispersion, completely immersing hydrophilic rigid foam in graphene oxide dispersion, freeze drying the hydrophilic rigid foam, and reducing the resultant product using hydrazine vapor. USE - Construction of graphene protective structure (claimed). ADVANTAGE - The method enables construction of graphene protective structure having excellent mechanical property, shear resistance and flexibility, and ultra-high specific surface area.
