▎ 摘　　要

NOVELTY - Preparing hydrophilic column (5)arene/three-dimensional reducing graphene oxide foam material comprises dispersing the water-soluble cationic hydrophilic column (5)arene into the graphene oxide aqueous solution, adding hydrazine hydrate and aqueous ammonia solution, stirring and mixing, and transferring to the reaction kettle for hydrothermal reaction at 90 degrees C for 3 hours, washing the hydrogel by centrifugation and pre-frozen by adding aqueous ammonia solution for 2 hours and freeze-drying for 48 hours. USE - The material is useful in electrochemical sensors, batteries and other conductive materials. ADVANTAGE - The material has conductivity of three-dimensional graphene, excellent hydrophilic properties of the hydrophilic column (5)arene, and porous structure.
