Abstract

The invention relates to graphene-based water-based conductive ink prepared by a one-step method and a preparation method thereof. The preparation method comprises the steps: jointly adding 1 to 8 parts of expanded graphite, 10 to 30 parts of conductive filler, 10 to 50 parts of water-soluble resin, 20 to 80 parts of solvent and 1 to 10 parts of aid into a high-pressure homogenizer to perform high-pressure shear; grinding until the particle size of slurry is smaller than 80mu m to obtain the graphene-based conductive ink with excellent conductivity and good stability. By means of the method, expanded graphite peeling and intercalation of conductive particles among graphite flakes can be finished at the same time in a shearing and grinding process; thus, an integrated good conductive network is established. The method has the advantages of simpleness in operation, short consumed time, ability in avoiding stack among the graphene flake layers and avoiding a grinding medium, simpleness infollow-up processing and suitability for production. The prepared graphene-based water-based conductive ink has the advantages of good dispersion and high stability.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, in particular to a one-step method for preparing graphene-based water-based conductive ink and a preparation method thereof. Background technique [0002] Conductive ink is a paste ink composed of conductive fillers, binders, solvents and additives, which has a certain degree of conductivity, commonly known as paste ink. Among them, the conductive filler is the most important component that determines the conductivity of the conductive ink. Graphene, as a new generation of two-dimensional carbon material with a single-layer sheet structure composed of carbon atoms, has many unique physical and chemical properties, and its theoretical specific surface area can reach 2600m 2 / g, the conductivity is as high as 1250~7000s / m; in addition, graphene also has excellent light transmission properties, good mechanical properties and thermodynamic stability, and is a good conductive ink filler....
