Problems solved by technology

However, the performance of the obtained laser-reduced graphene oxide (LrGO) is very unstable, and the laser processing process greatly damages the morphology of the GO film. It is difficult to obtain a graphene film with excellent performance, which cannot meet the preparation requirements of the electrode pattern.

Abstract

The invention discloses an energy-saving and environment-friendly preparation device for graphene electrode patterns, including a target component and a laser engraving machine. The target component includes a transparent substrate and a graphene oxide film placed on the surface of the transparent substrate, and pressure is set on the target component. The equipment applies pressure to the target component; the laser engraving machine applies laser radiation to the graphene oxide film after the pressure is applied to obtain the electrode pattern of the reduced graphene oxide. The graphene electrode pattern preparation method, the steps are as follows: place the transparent substrate that is pre-coated with GO film under the laser engraving machine; apply pressure to the GO film; start the laser engraving machine to irradiate the GO film under pressure to induce GO reduction yields graphene electrode patterns. Also includes repeated irradiation and reverse irradiation. Graphene electrode patterns for use in flexible electronics and wearable electronics. The LrGO obtained in the present invention has better electrical conductivity and lower surface roughness. The preparation is simple and fast, safe, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a preparation device, method and application of a graphene electrode pattern, in particular to a method for preparing an electrode pattern by laser-induced graphene, which belongs to the technical field of environmental protection and green energy. Background technique [0002] Graphene is a new type of two-dimensional carbon material, composed of carbon atoms in the form of sp2 hybrid orbitals to form hexagons, which are periodically arranged in a honeycomb shape. It was first obtained by A.K.Geim et al. in 2004 by the method of micromechanical exfoliation. Because graphene has the characteristics of high electrical conductivity, high mechanical strength, good flexibility, large specific surface area, and high chemical stability, it is used as an electrode in flexible touch screens, organic solar cells (OPV), organic electroluminescent devices (OLEDs) and other optoelectronic Wide range of applications. But so far, the graph...
