▎ 摘  要

NOVELTY - Graphite oxide is added to deionized water and ultrasonically dispersed. Ferrous salt and additive are added and uniformly mixed to obtain a solution (A). Sodium hydroxide is dissolved in deionized water and uniformly mixed to obtain a solution (B). The solutions (A,B) are slowly added and polyethylene glycol and hydrazine hydrate are dropped. The obtained product is re-dispersed in deionized water to obtain hydrazine precursor solution. The precursor solution is reacted at 80-100 degrees C for 8-12 hours, cooled, washed and dried to obtain iron oxide/graphene composite powder. USE - Manufacture of iron oxide/graphene composite oxide powder. ADVANTAGE - The iron oxide/graphene composite oxide powder is easily manufactured with high magnetization intensity. DETAILED DESCRIPTION - Graphite oxide is added to deionized water and ultrasonically dispersed. Ferrous salt and additive are added and uniformly mixed to obtain a solution (A). Sodium hydroxide is dissolved in deionized water and uniformly mixed to obtain a solution (B). The solutions (A,B) are slowly added at room temperature under continuously stirring, and active agent polyethylene glycol and hydrazine hydrate are dropped to produce black precipitate continuously. The obtained product is re-dispersed in deionized water to obtain hydrazine precursor solution. The precursor solution is reacted at 80-100 degrees C for 8-12 hours, cooled to room temperature, washed and dried to obtain iron oxide/graphene composite powder.
