Abstract

The invention discloses an electronic ink for inkjet printing and with no silver nano-wire sedimentation, and a preparation method thereof, and belongs to the field of electric-conduction inks, wherein the electronic ink comprises, by mass, 5-10% of silver nano-wires, 5-10% of a macromolecule electric-conduction polymer, 0.2-0.5% of a surfactant, 0.5-1.5% of a buffer agent, and the balance of deionized water. According to the present invention, during the preparation of the inkjet printing ink, the macromolecule electric-conduction polymer is added to increase the viscosity of the printing inkso as to improve the resolution of the printing line, further prevent the silver nano-wire sedimentation, and improve the electric conductivity and the reliability of the printing ink; and by addingthe surfactant and the buffer agent, the obtained ink has good time stability and good temperature stability.

Description

technical field [0001] The invention belongs to the field of conductive ink, and more specifically relates to an electronic ink for ink-jet printing of non-settling silver nanowires and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the demand-oriented requirements of miniaturization, thinning, and multi-functionalization of electronic equipment, the traditional printed circuit board (PCB) industry has been greatly impacted by new technologies, and it is urgent to inject new technologies to realize industrial upgrading. There are two hot development directions in the PCB industry in the future: 1. Flexible electronic devices, wearable electronic devices, etc., require new circuit boards to have excellent flexibility and bending resistance. 2. Fully transparent electronic equipment requires new circuit boards with high visible light transmittance. [0003] Inkjet printing technology has the advantages of digital...
