Embodiment

[0025] (1) Zirconium oxychloride octahydrate and polyethylene glycol 20000 are added to a mixed solvent of ethylene glycol and deionized water at a volume ratio of 1:1, the concentration of zirconium oxychloride octahydrate is 0.5M, polyethylene glycol The mass fraction of diol 20000 is 5%, and the zirconia inkjet printing ink is obtained by magnetically stirring and dissolving evenly and then aging for 24 hours. The obtained ink has a viscosity of 13-16 cps and a surface tension of 35-40 dyn / cm.

[0026] (2) Fill the ink obtained above into the cartridge of an inkjet printer. The printer used is Dimatix2800, and the substrate used is glass. When printing, the glass substrate should be kept at 50-60°C, the ink drop speed is 10m / s, and the nozzle does not heat up. The distance between ink droplets can be 20-45 μm. Then the printed film is heat-treated, and the heat treatment adopts the gradient heating mode. The heat treatment temperature of the printed film is first raised to...

Abstract

The invention belongs to the technical field of printed electronics, and discloses zirconium oxide inkjet printing ink as well as a preparation method and application thereof. The zirconium oxide inkjet printing ink comprises zirconium oxychloride octahydrate, polyethylene glycol, ethylene glycol and deionized water. The zirconium oxide inkjet printing ink is added into an inkjet printer, ink jetprinting is performed on a 50-60 DEG C glass substrate to obtain a film, and then the film is heated to 300-400 DEG C for heat treatment for 1-2 hours to obtain a porous zirconium oxide film. According to the invention, through selection and collocation of a solvent and a polymer, the zirconium oxide inkjet printing ink has proper viscosity and surface tension and can better meet inkjet printing requirements.

Description

technical field [0001] The invention belongs to the technical field of printed electronics, and in particular relates to a zirconia inkjet printing ink and a preparation method and application thereof. Background technique [0002] The existing inkjet printing process for processing oxide films mainly adopts a system containing a small molecule solvent and a small amount of polymer dispersant, which is sintered at high temperature to form a dense and high-purity oxide film, or sintered at low temperature to form a polymer- oxide composite films. And by introducing a certain amount of polymer into the system, it can affect the microstructure of the film, and it can be removed during the sintering process, and the oxide film can form a porous structure. This process has been widely used in spin-coating and dip-pulling methods, but there are few reports in the field of inkjet printing. This is because the physical properties of the above-mentioned solution system do not stric...
