Abstract

The invention belongs to the field of function materials, and relates to conductive ink, in particular to waterborne graphene colorful conductive ink. The waterborne graphene colorful conductive ink is specifically prepared from the following components in parts by mass: 10 to 20 parts of graphene waterborne composite slurry, 70 to 80 parts of connecting resin, 5 to 15 parts of a solvent, 1 to 5 parts of an aid, and 1 to 5 parts of color paste. A traditional organic solvent is replaced with deionized water serving as a dispersing medium, inorganic waterborne dye is used, and the adhesive force and the flexibility meet requirements by filtering the connecting resin and adjusting the proportion; meanwhile, graphene components are added, thereby effectively improving the conductive stability, reducing the electrical resistivity, and overcoming the defects of environmental pollution and high cost in a usage process of traditional solvent-type colorful conductive ink. A detection result shows that the waterborne graphene colorful conductive ink not only has the advantages of safety and environmental protection, but also has great conductivity.

Description

technical field [0001] The invention belongs to the field of functional materials and relates to conductive ink, in particular to a water-based graphene colored conductive ink. Background technique [0002] Conductive ink is a paste ink made of conductive material dispersed in a binder. It has a certain degree of conductive properties and can be used for printing conductive points or conductive lines. With the development of the electronic industry, the combination of electronic technology and printing technology is getting closer, the demand for conductive ink is also increasing, the application range is also increasing, and the problem of single color is becoming more and more obvious. Most of the currently used colored conductive inks are solvent-based, and solvent-based inks have the problem of volatile organic compounds (VOC) emissions. With the gradual enhancement of people's awareness of environmental protection, there is an urgent need in the market for a color con...
