▎ 摘 要
NOVELTY - The method for preparation of foamed graphene involves adding (i) oxidized graphite and polypropylene to ball mill, ball milling, adding mixed solution of ethanol and water, ultrasonically dispersing to form suspension, (ii) immersing foam nickel in suspension, evaporating solvent, introducing hydrogen and nitrogen mixture for muffle furnace reaction, natural cooling, (iii) immersing the obtained product in hydrochloric acid to obtain final product. USE - Method for preparation of foamed graphene (claimed). ADVANTAGE - The method enables simple preparation of foamed graphene.
