Embodiment 1

[0030] Mix 15ml of 2-amino-2-methyl-1-propanol and 22.5ml of methanol evenly, stir for 30 minutes, add 4g of silver carbonate, continue stirring until completely dissolved, and then filter through a 0.22um pinhole filter , to obtain orange-yellow conductive ink.

[0031] The thermal analysis curve of the obtained ink is as follows figure 1 As shown, it can be seen from the figure that the silver content is about 13%. The obtained ink was dropped on a glass slide, and after sintering at 90°C for 20 minutes, the surface morphology was as follows: figure 2 shown. The sheet resistance was 0.019Ω / □. The viscosity of the ink measured by a Brookfield LV-II rotational viscometer is 5.2 cP.

[0032] Put the prepared ink into the Epson R230 printer ink cartridge, print twice and then heat-treat at different temperatures and different times, the relationship between the sheet resistance and temperature and time is as follows image 3 shown.

Embodiment 2

[0034] Mix 15ml of 2-amino-2-methyl-1-propanol and 15ml of methanol evenly, stir for 30min, add 4g of silver carbonate, continue stirring until completely dissolved, then filter through a 0.22um pinhole filter membrane, An orange-yellow conductive ink is obtained.

[0035] Add a small amount of surfactant and viscosity modifier to the above ink. The viscosity of the ink measured by a Brookfield LV-II rotational viscometer is 8.3 cP. After heat treatment at 140℃ for 10min, the sheet resistance is 0.035Ω / □. Carry out XRD characterization to the obtained silver film, as Figure 4 shown.

Embodiment 3

[0037] Mix 12ml of 1-amino-2-propanol and 24ml of methanol evenly, stir for 30min, add 4g of silver carbonate, continue stirring until completely dissolved, then filter through a 0.22um pinhole filter to obtain orange-yellow conductive ink .

[0038] Add a small amount of surfactant and viscosity modifier to the above ink. The ink has a viscosity of 4 cP as measured by a Brookfield LV-II rotational viscometer. After heat treatment at 140℃ for 10min, the sheet resistance is 0.045Ω / □.

Abstract

The invention relates to the technical field of conductive inks, in particular to a low-temperature-sintered organic metal conductive ink and a preparing method thereof. The low-temperature-sintered organic metal conductive ink is characterized by comprising, by weight, 10%-25% of silver salt, 30%-60% of solvent, 20%-40% of complexing agent, 0.1%-5.0% of viscosity modifier and 0.1%-3.0% of surface active agent. Compared with the prior art, the good-stability low-temperature-sintered organic metal conductive ink and the preparing method thereof are provided, and the conductive ink can have the good electrical conductivity at the low sintering temperature, can be printed on multiple base materials, and can be used for flexible electronic printing.

Description

technical field [0001] The invention relates to the technical field of conductive ink, in particular to a low-temperature sinterable organic metal conductive ink and a preparation method thereof. Background technique [0002] With the demand for high precision and high integration of electronic equipment, inkjet printing technology has gradually emerged in the field of printed electronics. Because inkjet printing can realize on-demand inkjet, and it is fast and convenient. Compared with traditional stencil printing, it can reduce the waste of raw materials, so it has attracted the research of relevant personnel from all walks of life. In inkjet printed electronics, the main concerns are printers, inks and substrates. There must be good adaptability among the three to get a device with good performance. In order to achieve high precision, the aperture of the nozzle of the inkjet printer should be as small as possible. In this regard, there are already 1pl ink cartridges on ...
