Abstract

The invention provides a preparation method of a graphene circuit board. A positive electrode circuit with a voltage, a conductive metal negative-electrode substrate, and an oxide graphene solution coating layer coating the negative-electrode substrate are arranged. When the positive electrode circuit is connected, electric conduction with the negative-electrode substrate is realized to generate currents; and reduction of the oxide graphene solution on the negative-electrode substrate to graphene is carried out, so that reduction of a graphene layer on the negative-electrode substrate is realized. Because of XY addressing of the positive electrode, a graphene trajectory pattern layer can be formed on the negative-electrode substrate in accordance with a set circuit route. After corrosion of the negative-electrode substrate, a graphene circuit pattern is formed, so that a graphene circuit board is obtained. With the method provided by the invention, prototype manufacturing of the graphene circuit board as well as prototype drawing and manufacturing of the circuit pattern and line of the graphene circuit board can be carried out rapidly. Moreover, the method having simple steps can be implemented rapidly; and because no chemical medicine is employed during the preparation process, environment-friendly and pollution-free effects can be realized.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of carbon materials, and in particular relates to a preparation method of graphene oxide. [0003] 【Background technique】 [0004] Graphene is the only two-dimensional free-state atomic crystal discovered so far, and it is the basic structural unit for constructing zero-dimensional fullerenes, one-dimensional carbon nanotubes, and three-dimensional graphite. It has unique physical and chemical properties such as high electrical conductivity, high thermal conductivity, high hardness and high strength, and has broad application prospects in the fields of electronics, information, energy, materials and biomedicine. [0005] Graphene may replace silicon as the basic material of the next-generation semiconductor industry in the future, and it has different excellent properties. Graphene has a much higher carrier mobility than silicon. Graphene has a high-speed electron mobility of 200,000 cm2 / V s at room...
