Abstract

The invention discloses conductive ink based on a graphene composite material and a preparation method thereof. The conductive ink is prepared from the following components in parts by mass: 1-30 parts of a functional graphene composite material, 1-70 parts of a resin coupling agent, 5-60 parts of a solvent and 1-40 parts of an auxiliary. According to the method, graphene is modified into a functional graphene composite material, low density and high conductivity of graphene can be maintained, the situation that graphene is easily agglomerated and difficult to disperse can be improved, and then affinity between conductive filler and a resin connecting material is improved, so that the high-conductivity conductive ink under a low-content conductive agent can be successfully prepared. The conductive ink is simple in preparation method, stable in system, good in conductivity and easy to print, has a flexible and abrasion-resistance membrane layer, can be widely applied to radio frequency tags, intelligent package, film switches, conductive circuits, sensors and other light flexible electronic products, and has a huge market prospect.

Description

technical field

[0001] The invention relates to a conductive ink, in particular to a conductive ink based on a graphene composite material and a preparation method thereof. Background technique

[0002] Conductive ink is an ink made of conductive materials. It is widely used in printing conductive points and conductive circuits. It has a certain degree of conductive properties. It mainly includes gold-based conductive inks, silver-based conductive inks, copper-based conductive inks, and carbon-based conductive inks. etc., and these conductive inks have reached practical use. Conductive ink is composed of conductive fillers, binders, solvents and additives. The conductive fillers are usually gold powder, graphite, carbon black (special conductive carbon black is now available), carbon fiber, nickel powder, etc. The binder is mainly Epoxy resin, alkyd resin, acrylic resin, polyurethane resin, melamine formaldehyde resin, phenolic resin, vinyl chloride-vinyl acetate copolymer ...
