▎ 摘 要
NOVELTY - Manufacture of graphene foam involves adding a graphite oxide and a polyacrylonitrile into a ball mill for ball milling, and adding a ball-milled mixture into a mixed solution of an ethanol and water for ultrasonic dispersion to form a suspension, immersing a nickel foam in the suspension, steam-drying the solvent, adding a gas mixture of hydrogen and nitrogen to protect a reaction within a muffle furnace and reacting to completion followed by natural cooling, and immersing the resulting product in hydrochloric acid, performing a reaction, and reacting to completion. USE - Manufacture of graphene foam. ADVANTAGE - The method enables efficient manufacture of the graphene foam using a simple and easily operable equipment.
