Embodiment Construction

[0020] The technical solutions of the present invention, if not specified, are conventional solutions in the art; the reagents or materials, if not specified, are all derived from commercial channels

[0021] Preparation of nano silver particle type conductive ink components: weigh 0.1~19.0g silver nitrate, 1.0~2.0g polyvinylpyrrolidone (PVP), measure 20~40 ml ethylene glycol (Ethylene Glycol, EG) , add silver nitrate and PVP to ethylene glycol, stir or ultrasonically assist until the silver nitrate and PVP are completely dissolved, take it out after microwave heating for 40-100s and cool to room temperature, and then get nano-silver particle conductive ink, which can be used directly. The conductive components are nano-silver particles of various scales, which can be patterned on flexible substrates by various printing techniques, but the pattern after drying is not conductive, because the polymer coated on the surface of the particles makes the pattern must be sintered. The ...

Abstract

Nano-silver particle mixed conductive ink doped with organic silver and a preparation method thereof are disclosed. The advantage of low-temperature reduction (sintering) of organic silver precursor ink is utilized, the organic silver precursor ink is doped into nano-silver particle conductive ink to prepare mixed ink. On one hand, compared with the organic silver precursor ink, the mixed ink hasreduced requirements on storage conditions; on the other hand, compared with the traditional nano-silver particle type ink, the mixed ink has lowered sintering temperature, and can achieve room-temperature or low-temperature sintering, so that the device preparation process is simplified, and the selection range of a substrate material is widened. Nano-silver particles are generated in situ in thedrying process of patterns prepared by the mixed ink, so that the content of silver in the ink can be greatly reduced, and the cost of the ink is reduced.

Description

technical field [0001] The invention relates to the technical field of silver ink preparation, in particular to a nano-silver particle mixed conductive ink doped with organic silver and a preparation method thereof. Background technique [0002] Printed electronics is an emerging field resulting from the combination of traditional printing technology and electronic technology. The rise and development of this field makes electronic devices tend to be flexible, lightweight, and foldable. Flexible devices are prepared by printing (printing) technology and connected with various functional components, and their development depends on the development of various functional inks and conductive inks. Among the many types of conductive inks, they can be divided into inorganic conductive inks, organic conductive inks and composite conductive inks according to the conductive components of the ink. Among them, inorganic conductive inks include metal-based and carbon-based inks. Silver...
