Problems solved by technology

As people's demand for the functionality of electronic products continues to increase, conductive ink, as one of the key factors in inkjet printing technology, has also developed rapidly. In recent years, nano-metal particle inks and conductive polymer inks have appeared, such as traditional metal nano Particle inks are unstable in common solvents and easy to coagulate. Conductive polymer inks, such as polyaniline, have low conductivity and unstable chemical properties.

Abstract

The invention discloses digital ink-jet conductive ink and a preparation method thereof. The ink is prepared from pigments, graphene, a hyperbranched polymer, hyperbranched polymerization nano conductive particles, a photosensitizer and a solvent; uniform dispersion of graphene and a conductive particle solution is realized with a blending technology, and the prepared ink has good stability and redispersibility. The preparation method is simple; compared with conventional ink, the digital ink-jet conductive ink has the advantages of being high in conductivity, thin in printing film layer, uniform, smooth and good in performance, is applicable to multiple printing processes and substrates and is particularly applicable to the field of intelligent textile.

Description

technical field [0001] The invention relates to an ink-jet conductive ink and a production method thereof, in particular to a digital ink-jet conductive ink and a preparation method thereof. Background technique [0002] Conductive ink refers to the ink printed on the substrate so that it has the ability to conduct current and eliminate the accumulated static charge. It is a key material in printed electronics technology. The improvement of the performance of conductive ink will definitely promote the development of high-end textile and electronic industries such as smart labels and smart textiles. As people's demand for the functionality of electronic products continues to increase, conductive ink, as one of the key factors in inkjet printing technology, has also developed rapidly. In recent years, nano-metal particle inks and conductive polymer inks have appeared, such as traditional metal nano Particle inks are unstable in common solvents and easy to coagulate. Conductiv...
