Abstract

The invention discloses a novel nano-silver conductive ink and a preparation method thereof. The novel nano-silver conductive ink comprises: 5%-70wt% of nano-silver, 5-70wt% of non-nano-silver additive and 5%-25wt% of ink carrier. The method is as follows: mixing nano-silver, non-nano-silver additives and ink in a certain order, and then ultrasonically dispersing and fully mixing. The conductive ink for inkjet printing disclosed by the present invention has good implementability, and the product has Low resistance, adjustable viscosity, easy spraying and other characteristics.

Description

Technical field [0001] The invention relates to a conductive ink formula for inkjet printing, and a preparation method thereof, more specifically, to a conductive ink with high nanometer metal content, high uniform dispersion, high electrical conductivity, adjustable viscosity, and simple process. Ink composition and method for its preparation. Background technique [0002] As printing technology cross-penetrates more and more with other industry technologies, a series of new cross-techniques have emerged. "Printable Electronics Technology" is the organic integration of printing technology and electronic technology, which is another major breakthrough in the current technological development. It is a new technology that makes various electronic circuits or devices on various substrates, especially flexible substrates, by printing technology, so that it has functions such as electronic transmission, signal emission, electromagnetic shielding, photoelectric conversion, etc., ...
