Description
Technical Field
The invention belongs to the technical field of conductive ink, and particularly relates to ink-jet nano silver rod conductive ink, and a preparation method and application thereof.
Background
With the development of information technology, researchers have developed a new field of electronic inkjet printing (electronic inkjet printing) by preparing functional ink by replacing pigments in conventional ink with functional materials and successfully applying the technology to the preparation of electronic products. Therefore, the inkjet printing technology for directly manufacturing a circuit on a substrate is receiving attention, and the traditional printed circuit industry uses the photolithography technology, which involves the processes of etching, metal deposition, electroplating and the like, and is accompanied by the generation of a large amount of toxic chemical wastes. The nano metal ink-jet printing technology only needs two steps of printing and coating post-treatment when electronic products are produced, so that the preparation process is greatly simplified, the production efficiency is improved, and waste and pollution are avoided. Compared with the traditional electronic product manufacturing technology such as photoetching (photolithiography), the electronic ink-jet printing has the characteristics of non-contact, addition type, low cost and the like, so that the large area production of electronic products and the flexibility of substrates become possible; compared with traditional printing processes such as screen printing and the like, the ink-jet printing does not need a screen printing plate, so that the research and development cost of new products is reduced, and in addition, the ink-jet printing has obvious advantages in the aspects of resolution and multi-layer printing.
With the rapid development of ink-jet printed electronic technology, the related printed electronic materials attract the attention of people, and especially the conductive ink which is the core component of the ink-jet printed electronic technology has been developed at home and abroad. The conductive ink is used as a basic material of a conductive pattern, is a bottleneck of the development of a printed electronic technology, and directly influences the performance and quality of an electronic product. The common conductive components include nano-metals, conductive polymers, carbon materials, and the like. The nano metal has the outstanding advantages of small size, low melting point, excellent performance after sintering and the like, and can be smoothly sprayed out from a micron-sized diameter nozzle of an ink-jet printer, so that the nano metal can be widely used for conductive ink-jet as a conductive filler.
Silver has the characteristics of higher electrical conductivity and thermal conductivity, excellent physical and chemical properties, acceptable price, easy processing, certain electrical conductivity of oxides of the silver, and the like, and is widely used as a conductive component of conductive ink. For example, CN109535849A discloses an inkjet nano silver conductive ink and a preparation method thereof, comprising the following components: 12-30 parts of nano silver, 55-80 parts of deionized water, 0.02-2 parts of cosolvent, 0.1-1.0 part of wetting dispersant, 0.4-3.0 parts of binder, 0.2-0.6 part of defoamer, 3.0-10.0 parts of humectant and 0.5-0.6 part of viscosity regulator. CN102382502A discloses an inkjet nano-silver conductive ink and a preparation method thereof. The ink-jet nano silver conductive ink comprises the following components in percentage by mass: 2-20% of nano silver particles with the surface coated with an organic protective agent and the particle diameter of less than 50nm, 2-10% of energetic additive, 50-90% of ink solvent, 0.1-5% of surface tension regulator, 4-20% of tackifier and 0.01-0.1% of preservative.
However, the nano silver is easy to migrate on the insulator, so that the insulation resistance value between the electrodes is reduced, and finally, a short circuit is formed, namely, the phenomenon of silver migration is formed; after silver is dissociated into silver ions, the silver ions migrate from a high potential to a low potential and form flocculent or branched channels, which, when severe to a certain extent, may cause the device to fail. However, the migration of silver ions must be completed in a certain medium, that is, an electrolyte material including water vapor, most polymers/high molecular materials and individual inorganic materials, etc., silver ions will grow a dendritic structure like "swimming" in these media under the action of an electric field, which is also a reason why a touch screen is easy to lose its touch function after being electrified for a certain time.
