Problems solved by technology

Since the high-quality nano-silver wire is colorless and transparent or light-colored and transparent, it cannot be recognized visually or by instruments in the process of implementing printed circuits, especially for small circuits below a millimeter, so the detection process in the device production process is relatively cumbersome

preparation example Construction

[0009] The invention provides a method for preparing a fluorescent nano-silver wire transparent conductive liquid, which is characterized in that an organic fluorescent dye is added to the nano-transparent conductive material and a curing agent, an adhesion promoter, an anti-precipitation agent, etc. are added in a certain proportion , to prepare transparent conductive liquid with fluorescent silver nanowires. Then after the printed transparent circuit is dried, the printed state of the circuit can be directly observed; then the accelerator, diluent, and fluorescent quencher are mixed evenly in proportion and printed on the transparent circuit. After drying, the fluorescent dye can be removed. Purpose.

[0010] A method for preparing a fluorescent nano-silver wire transparent conductive liquid is mainly divided into two parts. The first part is to prepare a fluorescent nano-silver wire transparent conductive liquid; the addition amount of the nano-silver wire is controlled at ...

The nanometer silver wire transparent conductive liquid comprises a nanometer transparent conductive material, an organic fluorescent dye, a curing agent, an accelerator, a deposition prevention agent, an adhesion promoter, a diluent, a fluorescent quenching agent and is characterized in that the nanometer conductive material is a conductive material with nanometer silver wires as conductive filler, with resin as a carrier and with alcohol as a solvent, the organic fluorescent dye is a fluorane derivative type fluorescent dye or an organic fluorescent pigment, and the fluorescent characteristic of the nanometer transparent conductive material with fluorescence can disappear at 100-120 DEG C after secondary heating.

Description

technical field [0001] The invention belongs to the technical field of light-emitting display applications. Background technique [0002] The transparent conductive substance in the electronic light-emitting display lighting device is an important basic material, which can be widely used in liquid crystal display, OLED, electroluminescence and other fields. In the prior art, ITO material is mainly used to form through vacuum coating, and then photoetching matrix pixel electrodes. The technology of realizing transparent conduction through printing in a simple way is one of the key research directions. Among them, the technology of nano-metals for transparent electrodes is becoming more and more mature. For example, nano-silver and fluorescent preparation technologies have been widely used in biological detection and other fields. Stability issues cannot be used in electronics. Silver nano wire has excellent electrical conductivity, and it is one of the important ways for pe...
