Abstract

The invention discloses a preparation method of an iron and nickel graphene composite film. The preparation method comprises the following processes that (1) graphite oxide nano paste, ferroferric oxide nano paste and nickel oxide nano paste are sequentially placed in a container and stirred at the high speed; (2) an auxiliary is added, and even stirring is conducted; (3) a mixture is placed on asilicon-based flat plate, and flat laid evenly, and after still standing is conducted for five minutes, the mixture is covered with another silicon-based flat plate; and (4) an sandwich silicon-basedflat plate is placed in a microwave oven to be heated for 5-10 minutes, and after materials are cooled, a product, namely the iron and nickel graphene composite film can be obtained. The preparation method of the iron and nickel graphene composite film has the characteristics that the mass ratio of the added ferroferric oxide nano paste to the added nickel oxide nano paste to the added graphite oxide nano paste is (40 to 60):(20 to 30):1; a reduction mode is that the microwave heating temperature is 200-400 DEG C; a reducing agent can be hydroiodic acid, hydrobromic acid and hydrazine hydrate;and the silicon-based flat plates are made of quartz materials.

Description

technical field [0001] The invention relates to a graphene composite film of iron and nickel, which belongs to the field of new functional materials. Background technique [0002] The invention patent relates to the properties of iron, nickel and graphene. [0003] Iron is a common metal element. Iron with high purity is white or silvery white with metallic luster. High melting and boiling point, soluble in medium and strong acids, insoluble in water. Iron has multiple valence states, which can be transformed into each other under certain conditions. The physical and chemical properties of iron in different valence states are different. This can be used to adjust the properties of iron-containing compounds. The content of iron in the earth's crust is 4.75%, which is the fourth most abundant element in the earth's crust. High-purity iron has good flexibility and ductility, and can be used to manufacture the cores of motors and generators. In addition to being used as m...
