▎ 摘 要
NOVELTY - A porous surface of polymer microspheres having an amino group is added and soaked in a sulfonated graphene aqueous solution, stirred for 1 hour or more and dried at 50-90 degrees C, to obtain graphene-surface-coated sulfonated polymer porous microspheres. The graphene-surface-coated sulfonated polymer porous microspheres is carbonized in protective atmosphere at 500-1200 degrees C for 0.5 hour or more, to obtain graphene-surface-coated porous carbon microspheres. USE - Preparation of graphene-surface-coated porous carbon microspheres used for apparatus (claimed) and catalyst for lithium-ion battery, supercapacitor and adsorption, desalination and sensing applications. ADVANTAGE - The method enables preparation of graphene-surface-coated porous carbon microspheres having large surface area, high electron mobility rate and conductivity with high yield and reaction controllability, by simple method.
