Problems solved by technology

In order to achieve the anti-oxidation effect, some research groups try to wrap Ni on the outside of Cu nanowires. Although the electrical stability and oxidation resistance of Cu nanowires coated with Ni are improved, as the concentration of Ni wrapping increases, the Cu nanowires The resistance of the wire is also increasing

Embodiment Construction

[0025] Firstly, Cu nanowire thin film electrodes were fabricated by suction filtration imprinting technique.

[0026] 1) Take 50mg of Cu nanowires, disperse them in 10ml of n-hexane after ultrasonic oscillation for 20min, take 0.5ml from it, dilute to 30ml with n-hexane, and ultrasonically vibrate for 20min. Then measure 10ml of the solution and add it dropwise to the container on the nitrocellulose membrane. Using a vacuum filter (such as figure 1 As shown in the first step), turn on the vacuum mechanical pump for 3s, and filter the n-hexane solvent through the nitrocellulose membrane to form a uniform Cu nanowire film with a certain humidity. The main point of this technology is that the concentration and volume of the solution must be precisely controlled, and the vacuum filtration time (this time is proportional to the volume of the solution) must be accurately controlled. After the filtration, the Cu nanowire film still maintains a certain humidity, so that the subsequen...

Abstract

The invention relates to manufacturing of metal transparent film electrodes, in particular to a manufacturing method of a copper nano wire network wrapped by a graphene carbon film. According to the manufacturing method of the copper nano wire network wrapped by the graphene carbon film, oxidation resistance and the optical-electrical characteristic of copper nano wire electrodes can be effectively improved. The manufacturing method includes the steps that the copper nano wire film electrodes are manufactured; graphene is grown on copper foil at low temperature; the vacuum melting point of copper nano wires is regulated and controlled; the copper nano wire network is wrapped by the graphene carbon film. The sample is sealed through a copper foil capsule, by using the method of strictly controlling the curing time and the reaction time of the sample through a magnetic force rod, the profile of the copper nano wires at high temperature can be kept stable, rapid cooling and annealing treatment after the graphene carbon film is wrapped can be finished, and therefore the surfaces of the whole side walls of the copper nano wires can be evenly wrapped by the graphene carbon film within the effective time to form a coaxial wrapped structure.

Description

technical field [0001] The invention relates to the preparation of a metal transparent film electrode, in particular to a preparation method of a copper nanowire network wrapped by a graphene carbon film. Background technique [0002] Transparent electrodes are widely used in conductive layers of devices such as flat panel displays, touch screens, OLEDs, LEDs, smart windows, and solar cells. Traditional transparent electrodes generally use ITO, AZO, etc. These electrode materials are often expensive due to complex manufacturing processes and harsh conditions. With the development of electronic technology, the demand for transparent conductive electrodes will increase day by day in the future. Moreover, because people have put forward certain requirements for the flexibility of devices, researchers have gradually begun to explore some new materials, such as carbon nanotubes and graphene. However, the transparent conductive films made of these materials generally have a rela...
