▎ 摘　　要

NOVELTY - The method involves adding a part by weight of oxidized graphene carbon, adding 100-200 parts by weight of ethylene glycol in a reactor, adding 0.1-10 parts by weight of ferrous inorganic compound and basic hydroxide, and centrifugalizing, washing and drying to acquire a magnetic conductive multifunctional graphene composite material. A raw material of graphene is selected from graphene after an oxidizing process. The ethylene glycol is selected from diethylene glycol, triethylene glycol, tetraethylene-glycol or pentathylene-glycol. USE - Method for preparing a magnetic conductive multifunctional graphene composite material that is utilized in a biomedicine field and a micro-nano electron field. ADVANTAGE - The method enables proving simple and easy operation and providing high controllability for mass production. The acquired functional graphene composite material has super-paramagnetism, electrical conductivity and workability functions, and has wide application range in fields such as biomedicine and micro-nano electron. DETAILED DESCRIPTION - The ferrous inorganic compound is selected from ferric chloride, ferric nitrate, ferric sulphate, ferrous chloride, ferrous nitrate or ferrous sulphate. The basic material is selected from sodium hydroxide or potassium hydroxide. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of a method for preparing a magnetic conductive multifunctional graphene composite material.
