▎ 摘　　要

NOVELTY - Preparing different-size graphene oxide composite super thermal agent comprises adding aqueous solution of oxidized graphene quantum dot in aqueous dispersion liquid of nano aluminum powder and mixing, then adding aqueous dispersion of nano-sized metal oxide MOx/2 or nanocomposite GO/MOx/2 of oxidized graphene material and metal oxide and reacting to obtain Al/GO/MO x/2 composite materials with different sizes of graphene materials, where the metal element M is copper, iron, cobalt, nickel, magnesium, manganese, tungsten, lead or bismuth and x is chemical valence of M having value of 2-7. USE - The method is useful for preparing different-size graphene oxide composite super thermal agent (claimed). ADVANTAGE - The method has simple operation, economy and environmental protection, and the agent has high heat release, good dispersivity, high activity, and good stability.
