Embodiment 1

[0048] ZnO nanoparticles are prepared by liquid phase method (the existing technology has been published, so I won’t go into details here)

[0049] The low-boiling point alcohol solvent uses methanol, the boiling point is 64.7°C, the viscosity is 0.59 (20°C), and the density is 0.79 g / ml; the high-boiling point alcohol solvent uses ethylene glycol, the boiling point is 197°C, the viscosity is 19.9 (20°C) , with a density of 1.12 g / ml.

[0050] The ZnO nanoparticle solution prepared by the liquid phase method was added with a precipitant, centrifuged and dried to obtain the ZnO nanoparticle, and 1 g of the ZnO nanoparticle was weighed for use. Measure 62.7 ml (49.5 g) of methanol and pour it into a 200 ml single-necked flask, then pour 1 g of ZnO nanoparticles into the methanol, and shake or stir fully to disperse the ZnO nanoparticles into the methanol. Finally, 44.2 milliliters (49.5 grams) of ethylene glycol was added, and fully oscillated or stirred to prepare 107 millilit...

[0052] Zn x Mg 1-x O nanoparticle ink

[0053] Zn x Mg 1-x O nanoparticles can be prepared by liquid phase method (the prior art has been published, so I won’t go into details here)

[0054] The low-boiling point alcohol solvent is ethanol, with a boiling point of 78.3°C, a viscosity of 1.17 (20°C), and a density of 0.79 g / ml; a high-boiling point alcohol solvent is n-octanol, with a boiling point of 195°C and a viscosity of 8.71 (20°C). , with a density of 0.83 g / ml.

[0055] Zn prepared by liquid phase method x Mg 1-x The O nanoparticles solution was added with precipitant and centrifuged and dried to obtain Zn x Mg 1-x O nanoparticles, weighed Zn x Mg 1-x O nanoparticle 1 gram, stand-by. Measure 25.1 ml (19.8 g) of ethanol and pour it into a 200 ml one-necked flask, then add 1 g of Zn x Mg 1-x Pour the O nanoparticles into ethanol and shake or stir well to make the Zn x Mg 1-x O particles dispersed in ethanol solution. Finally, 95.4 ml (79.2 g) of n-octanol ...

Abstract

The invention discloses a zinc-oxide-based nanometer particle ink and a preparation method thereof. The zinc-oxide-based nanometer particle ink comprises the following components, by weight percentage, 0.01-20.0% of zinc-oxide-based nanometer particles and 80.0-99.99% of a solvent. The solvent comprises at least one low-boiling-point alcohols solvent and at least one high-boiling-point alcohols solvent, wherein the amount of low-boiling-point alcohols solvent is 1.0-80.0% of the total amount of the solvent. According to an ink formula in the invention, zinc-oxide-based nanometer particles can be dispersed in the solvent, and the viscosity of the solvent is improved and the volatilization speed of the solvent is lowered by adjusting low-boiling-point alcohols with high-boiling-point alcohols. The ink can meet the index requirements, such as ink viscosity and volatilization speed, of ink-jet printing, and zinc-oxide-based nanometer particles of the ink can be uniformly stably dispersed in the solvent.

Description

technical field [0001] The invention relates to the field of ink for inkjet printing, in particular to a zinc oxide-based nano particle ink and a preparation method thereof. Background technique [0002] Zinc oxide is a kind of II-VI compound semiconductor material with wide bandgap and direct bandgap. The bandgap width at room temperature is 3.37eV. It is an important semiconductor optoelectronic material. Electrically behaves as an n-type conductivity type with a resistivity as low as 10 -4 Ω / cm.
