Abstract

The invention discloses a nanometer silver wire inkjet electric conduction ink preparation method, which is characterized in that ultrasonic oscillation and centrifugal separation are combined to obtain the nanometer silver wire with a diameter of 30-60 nm and a length of 2-4 [mu]m; with the application of the nanometer silver wire as the electric conduction component, the high electric conductivity under the low electric conduction component content condition can be achieved, and the good stability and the good rheological behavior can be achieved so as to easily achieve the inkjet printing of the electric conduction line; and the components of the nanometer silver wire inkjet electric conduction ink comprise, by mass, 0.8-2% of nanometer silver wire, 0.01-0.08% of polyvinyl pyrrolidone K90, 78-87% of isopropyl alcohol, 8-15% of diethylene glycol, and 3-6% of diethylene glycol monobutyl ether.

Description

technical field [0001] The invention relates to a preparation method of nano-silver wire ink-jet conductive ink. The conductive ink belongs to printed electronic paste and is applied in the field of inkjet printed electronic technology. Background technique [0002] Inkjet printing refers to the technology of controlling inkjet printing equipment with computer assistance, and is a non-contact and plate-free printing technology. Compared with traditional electronic product manufacturing methods, jet printing technology has the advantages of precise wiring at the corresponding position of the substrate, no need for plate making, and direct acquisition of target conductive patterns. Inkjet printed electronics technology has incomparable advantages in large area, flexibility, transparency, low cost and green environmental protection. With the rapid development of inkjet printed electronic technology, the related printed electronic materials have attracted widespread attention,...
