Water-based graphene conductive ink

Abstract

Belonging to the field of functional materials, the invention relates to conductive ink, particularly to a water-based graphene conductive ink. The water-based graphene conductive ink specifically comprises the following components by mass: 50-70 parts of a graphene composite slurry, 30-55 parts of connection resin, 5-10 parts of a solvent, and 2-10 parts of an assistant. The water-based graphene conductive ink provided by the invention adopts deionized water as the dispersion medium to replace traditional organic solvents, and through connection resin screening and proportion adjustment, the adhesion and flexibility of the ink both meet the requirements, also the added graphene component effectively improves the conductive stability and reduces the resistivity. The water-based graphene conductive ink provided by the invention overcomes the defects of environmental pollution during use and high cost of traditional solvent type conductive ink. The detection result shows that water-based graphene conductive ink not only has the advantages of safety and environmental protection, but also has good conductivity.

Description

technical field [0001] The invention belongs to the field of functional materials and relates to conductive inks, in particular to a water-based graphene 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 electronics industry, the combination of electronic technology and printing technology is getting closer and closer, and the demand for conductive ink is also increasing. Most of the conductive inks currently used 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 conductive ink that uses water as a solvent to replace the traditional conductive ink, in order to comply with the de...
