Problems solved by technology

[0002]At present, there are many types of enameled wires such as pure copper wire, alloy wire, copper-clad aluminum wire, etc., but they have many disadvantages: high resistivity, heavy weight, high brittleness, easy to Fracture etc.
[0003] At present, people have discovered a new material, graphene, which has high strength, high conductivity, good heat dissipation and light weight, but graphene is difficult to combine with finer materials wires, so there is a need for a production method for attaching graphene to thinner wires

Embodiment 1

[0018] Embodiment one: a kind of production method of graphene wire, it comprises the following steps:

[0019] 1) Stretch the copper material into a pure copper wire;

[0020] 2) Dissolving graphene oxide in water to make graphene oxide solution;

[0021] 3) A graphene oxide solution is evenly attached to the surface of the wire;

[0022] 4) Heat the wire attached to the graphene oxide solution in step 3) at a temperature of 100°C-700°C in a nitrogen-protected environment to reduce graphene oxide to graphene;

[0023] 5) Apply insulating varnish on the graphene-attached wire and bake it;

[0024] 6) Cool the wire and take it up.

[0025] In this embodiment, the graphene oxide solution is attached to the surface of the metal wire, and the graphene oxide solution is heated and reduced at a high temperature to produce a wire with graphene on the surface, which solves the technical problem that the graphene wire is difficult to produce.

Abstract

The invention discloses a production method for a graphene conductive wire. Graphene oxide is prepared into solution, and the solution is evenly adhered on the surface of metal wire material. The graphene oxide is reduced into graphene by adopting a high-temperature heating method, and the graphene is adhered on the surface of the metal wire material. The technical problem that the graphene conductive wire is difficult to produce is solved by the production method.

Description
