▎ 摘　　要

NOVELTY - A graphene oxide paper with surface microsphere structure involves distributing graphene oxide evenly with micron-level graphene oxide balls on surface, connecting tightly bottom of graphene oxide ball at lower part by graphene sheet, and having graphene oxide balls as hollow structure inside. USE - Graphene oxide paper with surface microsphere structure. ADVANTAGE - The graphene oxide paper with surface microsphere structure is evenly distributed with micron-scale graphene oxide balls on surface and this unique structure gives higher specific surface area than ordinary graphene oxide paper. By adjusting pH, concentration, content of graphene oxide dispersion, size and distribution of surface microspheres can be adjusted on micron scale. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide paper having surface microsphere structure involves using modified hummer method to prepare graphene oxide dispersion, adding prepared graphene oxide in concentration of graphene oxide dispersion reaches 2-3 mg/mL, taking 30-70 mL of obtained graphene oxide dispersion, adjusting pH of dispersion to 1-3, ultrasonically processing at 500W under ice bath for 10-30 minutes, filtering graphene oxide dispersion liquid by suction to form film, completing, drying to room temperature for 12-15 hours, maintaining suction filtration state during this period, closing suction filtration device, and maintaining room temperature left for 12-24 hours.
