Problems solved by technology

Nano-silver ink is generally printed by inkjet, but the nanoparticles in nano-silver ink may block the nozzle, and the dispersant added in the nano-silver solution will affect the electrical properties of the wire. In addition, the preparation of nano-silver requires the use of a high-speed centrifuge Or equipment with high energy consumption such as vacuum ovens, making it difficult to mass-produce nano-silver inks

Embodiment 1

[0025] Dissolve 0.01mol capric acid in a mixed solvent (45ml absolute ethanol, 5ml anhydrous ether), add 0.01mol triethylamine to form a salt. Then dissolve 0.01mol silver nitrate in 20ml mixed solvent (18ml absolute ethanol, 2ml anhydrous ether), and pour it into the previously configured solution. At this time, a large amount of decanoate silver-white precipitate will be produced, which is suction filtered, washed with ethanol and water, and dried in vacuum to obtain the final silver decanoate.

[0026] Add 0.005 mol of silver decanoate solid to 6.25 g of isopropanol, then add 0.01 mol of isopropylamine, and stir until all the solids are dissolved. A colorless and transparent solution is obtained.

[0027] The prepared ink was spin-coated on glass, heat-treated in an oven at 200oC for 30 minutes, taken out to room temperature and placed in acetone for 10 minutes. After drying, the resistivity was measured to be 3.3E-6Ω·cm.

Embodiment 2

[0029] Dissolve 0.01mol formic acid in a mixed solvent (45ml absolute ethanol, 5ml anhydrous ether), add 0.01mol triethylamine to form a salt. Then dissolve 0.01mol silver nitrate in 20ml mixed solvent (18ml absolute ethanol, 2ml anhydrous ether), and pour it into the previously configured solution. At this time, a large amount of silver formate white precipitate will be produced, which is suction filtered, washed with ethanol and water, and dried in vacuum to obtain the final silver formate.

[0030] Add 0.005 mol of silver formate solids to 1.18 g of ethylene glycol, then add 0.01 mol of ethanolamine, and stir until all the solids are dissolved to obtain a colorless and transparent solution, which is configured as a 30% solid content ink.

[0031] The prepared ink was spin-coated on glass, heat-treated in an oven at 160°C for 30 minutes, and then placed in acetone for 10 minutes after taking it out to room temperature. After drying, the resistivity was measured at 8....

Embodiment 3

[0033] Dissolve 0.01mol of isooctanoic acid in a mixed solvent (45ml of absolute ethanol, 5ml of anhydrous ether), and add 0.01mol of triethylamine to form a salt. Then dissolve 0.01mol silver nitrate in 20ml mixed solvent (18ml absolute ethanol, 2ml anhydrous ether), and pour it into the previously configured solution. At this time, a large amount of silver isooctanoate will be produced, which will be filtered with suction, washed with ethanol and water, and dried in vacuum to obtain the final silver isooctanoate.

[0034] Add 0.005 mol of silver isooctanoate solid to 4.86 g of cyclohexanone, then add 0.01 mol of butylamine, and stir until all the solids are dissolved to obtain a yellow transparent solution, which is configured as a 20% solid content ink.

[0035] The prepared ink was spin-coated on glass, heat-treated in an oven at 200oC for 30 minutes, taken out to room temperature and placed in acetone for 10 minutes. After drying, the electrical resistivity was me...

Abstract

The invention relates to a silver-organic conductive ink for printed electronics. The ink is a solution which is formed by dissolving a silver-organic compound in a specific solvent and can be subjected to ink jetting, gravure, silk screening to form conductive patterns. The silver-organic conductive ink comprises 10-60 wt.% of a saturated carboxylic acid silver compound, 5-50 wt.% of an amido compound, 10-85 wt.% of a solvent and 0-10 wt.% of a thickening agent, the saturated carboxylic acid silver compound comprises a linear chain, a branched chain and a hydroxyl, amido and sulfydryl substituted carboxylic acid silver compound, the amido compound is complex with carboxylic acid silver so as to improve dissolubility of the carboxylic acid silver, the amido compound is primary amine and secondary amine, the amido amount is two times of molar weight of silver ions, the solvent is not reacted with the carboxylic acid silver or amine, and the thickening agent is used for adjusting viscosity. The silver-organic conductive ink can be applied to preparation of conductive lines by means of methods of printed electronics and is capable of simplifying existing line preparation processes.

Description

Technical field [0001] The invention belongs to the field of printed electronics, and is specifically a silver organic conductive ink for printed electronics. Background technique [0002] The circuit manufacturing process in traditional printed circuit boards uses subtractive etching to etch circuit patterns on the copper clad board, which has many shortcomings such as high material consumption, multiple production processes, large waste liquid discharge, and heavy environmental protection pressure. The emerging printed electronic addition process is to use the printing process to quickly print functional inks or paddles on organic or inorganic substrates to form various electronic components and electronic circuits, with fewer production processes. The advantages of low production cost, environmental friendliness, flexible design, diversified functions, etc., have broad application prospects. [0003] The core of printed electronics technology is the preparation of functional ...
