Disclosure of Invention
In order to solve the technical problems, the application provides a zinc oxide-based nanoparticle ink.
According to one aspect of the present application, there is provided a zinc oxide-based nanoparticle ink comprising: a zinc oxide-based nanoparticle having a ligand that is a glycol, an alcohol amine of C2 to C4, or an amide of C1 to C4; the first solvent is alcohol ether and/or saturated monohydric alcohol with the boiling point of 160-250 ℃; a second solvent, the second solvent being a glycol; a third solvent, wherein the third solvent is saturated monohydric alcohol with a boiling point of 70-155 ℃; a fourth solvent which is fluorocarbon alcohol; the content of the first solvent is 40 wt% -60 wt%, the content of the second solvent is 1 wt% -10 wt%, the content of the third solvent is 10 wt% -30 wt%, and the content of the fourth solvent is 5 wt% -30 wt%.
The term "boiling point" as used herein, unless otherwise specified, refers to the boiling point of a material at 1 atmosphere.
It will be understood that although the terms first, second, third, etc. may be used herein to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from another.
In the zinc oxide-based nanoparticle ink composed of the above components, the zinc oxide-based nanoparticles can be uniformly dispersed, and the dispersion stability can be maintained for a long time. And the zinc oxide-based nanoparticle ink is smooth in printing in the ink-jet printing process, does not block a spray head in long-time continuous printing, and has no offset of the printing ink drop track. In addition, the zinc oxide-based nanoparticle ink has good wettability to the oleophilic quantum dot light-emitting layer, so that the film forming quality of the zinc oxide-based nanoparticle layer is higher.
In one embodiment, the fluorocarbon alcohol is a monohydric fluorocarbon alcohol of C3 to C9. The inventors found that the monohydric fluorocarbon alcohols of C3 to C9 are effective in adjusting the surface tension of the ink when used in combination with the first solvent, the second solvent, and the third solvent. Thus, by adding a proper amount of C3-C9 monohydric fluorocarbon alcohol into the ink, the ink has very good wetting property on the substrate of the quantum dot light-emitting layer. In addition, when the optical properties of the prepared quantum dot light emitting diode were tested, it was found that the use of the monohydric fluorocarbon alcohols of C3 to C9 did not deteriorate the electron transport properties of the electron transport layer.
In one embodiment, the C3-C9 monohydric fluorocarbon alcohol is 2,2,3, 3-tetrafluoro-1-propanol, 1, 3-difluoro-2-propanol, 4,4, 4-trifluoro-1-butanol, 2,3,4,4, 4-hexafluoro-1-butanol, 2,3,3,4,4, 4-heptafluoro-1-butanol, 1,1,1,3,3,4,4, 4-octafluoro-2-butanol, 4,4,5,5, 5-pentafluoropentanol, 2,3,3,4,4,5, 5-octafluoro-1-pentanol, 6- (perfluoroethyl) hexanol, 1H,2H, 2H-perfluorohexen-1-ol, 1H, 7H-dodecafluoro-1-heptanol, 2,3,3, 3-difluoro-2-propanol, 4,4, 5-heptafluoro-1-pentanol, 6- (perfluoroethyl) hexanol, 1H,2H, 2H-perfluorohexen-1-ol, 1H, 7H-dodecafluoro-1-heptanol, and mixtures thereof, At least one of 1H, 1H-perfluoro-1-heptanol, 4,4,5,5,6,6,7,7, 7-nonafluoro-1-heptanol, 1H,2H, 2H-perfluorooctanol, 2,3,3,4,4,5,5,6,6,7,7,8,8, 8-pentadecafluoro-1-octanol, 1,1, 1-trifluoro-2-octanol, 1H, 9H-hexadecafluorononol and 1H, 1H-perfluoro-1-nonanol.
In the application, the first solvent with a high content can be composed of alcohol ether alone or saturated monohydric alcohol with a boiling point of 160-250 ℃, or can be composed of a mixture of alcohol ether and saturated monohydric alcohol. In one embodiment, when the first solvent is a mixture of alcohol ether and saturated monohydric alcohol with a boiling point of 160-250 ℃, the content ratio of the saturated monohydric alcohol with a boiling point of 160-250 ℃ to the alcohol ether is 0.1-10.
In one embodiment, the alcohol ether is a C5 to C11 alcohol ether. The inventor finds that when alcohol ether with the carbon atom number less than 5 is selected as the first solvent, zinc oxide-based nanoparticles are easy to separate out from ink in the process of printing zinc oxide-based nanoparticle ink, so that a spray head is blocked. When the alcohol ether with the carbon atom number larger than 11 is selected as the first solvent, after the zinc oxide-based nanoparticle ink is printed on a substrate such as a quantum dot light emitting layer, the drying time is long, and the efficient film forming is not facilitated. On the other hand, when the alcohol ether of C5-C11 is selected as the first solvent, the zinc oxide-based nanoparticle ink is smooth in printing and high in film forming efficiency.
In one embodiment, the alcohol ether of C5 to C11 is one of a linear alcohol ether, a branched alcohol ether with one methyl group, a branched alcohol ether with one ethyl group, and any two or three mixtures. The inventors found that when the molecular structure of the alcohol ether contains a branch chain, especially the number of carbon atoms of the branch chain is more than 2, the dispersibility of the zinc oxide-based nanoparticles in the ink is poor; when the alcohol ether containing no branched chain or one methyl branched chain or one ethyl branched chain is selected, the dispersion stability of the zinc oxide-based nanoparticle ink can be effectively improved. Specifically, the alcohol ethers of C5 to C11 in the present application include, but are not limited to, ethylene glycol butyl ether, ethylene glycol monohexyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, triethylene glycol methyl ether, triethylene glycol ethyl ether, propylene glycol butyl ether, dipropylene glycol monoethyl ether, dipropylene glycol monobutyl ether, or ethylene glycol monoisooctyl ether.
In one embodiment, the saturated monohydric alcohol with the boiling point of 160-250 ℃ in the first solvent is a saturated monohydric alcohol of C7-C11. The inventor finds that when saturated monohydric alcohol with the carbon number less than 7 is selected as the first solvent, zinc oxide-based nanoparticles are easy to separate out from ink in the process of printing zinc oxide-based nanoparticle ink, so that a spray head is blocked. When the saturated monohydric alcohol with the carbon atom number larger than 11 is selected as the first solvent, after the zinc oxide-based nanoparticle ink is printed on a substrate such as a quantum dot light emitting layer, the drying time is long, and the efficient film forming is not facilitated. On the other hand, when the saturated monohydric alcohol of C7-C11 is used as the first solvent, the zinc oxide-based nanoparticle ink is smooth in printing and high in film forming efficiency.
In one embodiment, the monohydric alcohols of C7 to C11 include 5-methyl-2-hexanol, 2-methyl-2-hexanol, 4-methyl-1-hexanol, 3-methyl-3-hexanol, n-heptanol, n-octanol, n-nonanol, n-decanol, 1-undecanol, 2-heptanol, 4-heptanol, 3-methyl-1-heptanol, 5-methyl-2-heptanol, 6-methyl-2-heptanol, 2-methyl-2-heptanol, 5-methyl-3-heptanol, 3-methyl-2-heptanol, 2-methyl-4-heptanol, 2-octanol, 3-octanol, 4-octanol, 3, 7-dimethyl-1-octanol, 6-methyl-1-octanol, 2-nonanol, 3-nonanol, 4-nonanol, 5-nonanol, 2-decanol, 3-decanol, or 2-undecanol.
In one embodiment, the saturated monohydric alcohol with the boiling point of 70-155 ℃ in the third solvent is C3-C6 saturated monohydric alcohol. This application is through selecting for use the boiling point at 70~155 ℃ saturated monohydric alcohol as the third solvent, uses with first solvent collocation, especially when the boiling point of first solvent is greater than the third solvent, can realize that zinc oxide base nanoparticle ink solvent's gradient volatilizees to prepare high-quality zinc oxide nanoparticle layer.
In one embodiment, the monohydric alcohols from C3 to C6 are normal monohydric alcohols including n-propanol, n-butanol, n-pentanol, or n-hexanol. The inventors found that when the monohydric alcohol of C3 to C6 contains a branch in the molecular structure, especially when the number of carbon atoms of the branch is greater than 2, the dispersibility of the zinc oxide-based nanoparticles in the ink is poor.
In one embodiment, the boiling point of the glycol in the second solvent is 150 to 300 ℃. The inventors have found that when a glycol has a boiling point of less than 150 ℃, the zinc oxide-based nanoparticle ink is susceptible to clogging of nozzles when used for printing. When the boiling point of the diol is more than 300 ℃, the diol is less likely to be volatilized, resulting in difficulty in drying when the light emitting layer is prepared.
In one embodiment, the glycol of the second solvent is a glycol of C2 to C6, and when the glycol of C2 to C6 is used in combination with an alcohol ether of C5 to C11 or with a monohydric alcohol of C7 to C11, the glycol of C2 to C6 is effective to adjust the viscosity of the ink. Thus, the viscosity of the ink can meet the requirements of common ink-jet printers by adding a proper amount of C2-C6 diol into the ink. In addition, when the optical properties of the prepared quantum dot light emitting diode were tested, it was found that the use of the diols of C2 to C6 did not deteriorate the electron transport properties of the electron transport layer.
In one embodiment, the C2 to C6 diols include ethylene glycol, 1, 2-propanediol, 1, 3-propanediol, 1, 2-butanediol, 1, 3-butanediol, 1, 4-butanediol, 2, 3-butanediol, 1, 2-pentanediol, 1, 4-pentanediol, 1, 5-pentanediol, 2, 4-pentanediol, 2, 5-hexanediol, or 1, 6-hexanediol.
In one embodiment, the diol ligand of the zinc oxide-based nanoparticles is PEG200, PEG300, PEG400, or a diol having a carbon number of C2 to C6. The alcohol amine of C2 to C4 is ethanolamine, 3-amino-1-propanol, 2-amino-1-butanol or 4-amino-1-butanol. The amide of C1 to C4 is formamide, acetamide, propionamide, butyramide or isobutyramide. The inventor finds that when the substances are selected as the ligand of the zinc oxide-based nano-particles, the dispersion stability of the zinc oxide-based nano-particle ink can be obviously improved.
In one embodiment, the zinc oxide-based nanoparticles are present in an amount of 0.1 wt% to 10 wt%.
