Embodiment Construction

[0008] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0009] The invention provides a nano-copper oxide ink-jet ink formula, the ink-jet ink is composed of: 12% nano-copper oxide, 17% ethylene glycol, 4% PVP dispersant, 1.2% surfactant CTAB, PH regulator 0.7%, deionized water balance.

[0010] Wherein, the pH regulator is sodium bicarbonate.

[0011] The present invention provides a nano-copper oxide ink-jet ink formulation. Nano-copper oxide copper has similar electrical properties to other metals, and has a lower price, which is about 1 / 80 of silver, and in some humid environments, generally There is also no ion migration. The nano-copper oxide ink-jet ink prepared by using this formula can fully meet the production of functional conductive inks in printed electronics technology.

Abstract

The invention provides a formula of nano copper oxide jet ink. Nano copper oxide has similar electrical properties to other metals, has a low price about 1 / 80 of that of silver, and is generally free of ionic migration in some moist environments. The nano copper oxide jet ink prepared according to the formula is fully satisfactory to the production of printing electronics functional conductive inks.

Description

technical field [0001] The invention relates to an ink-jet ink formulation, in particular to a nano-copper oxide ink-jet ink formulation. Background technique [0002] Nano-metal conductive ink has the characteristics of small nano-particle size, low sintering temperature, and high conductivity after sintering. It can be used as the main functional ink of a new generation of printed electronics and can be used for mass production. Printed electronically conductive nano-metal ink is mainly composed of dispersed matrix, nano-metal particles and some additives. At present, the related nano-metal conductive inks prepared include nano-silver, nano-gold [0003] And other metal conductive inks. Among them, the research of nano-silver conductive ink is relatively mature now. However, people's demand for gold and silver has been increasing for a long time, and their prices are relatively high. In addition, if metallic silver is in a humid environment, it is particularly prone to...
