Problems solved by technology

Functional material inks for printing electronics are mainly divided into two types: particle type and particle-free type. Among them, the particle type ink is composed of metal oxide particles, dispersants, surfactants, solvents and other additives, which need to be sintered at a higher temperature, which limits its application on flexible substrates such as PET

Abstract

The invention provides zinc oxide ink for printed electronics and a preparation method and use method of the zinc oxide ink. The ink is prepared from, by mass, 10-50% of a chelating agent, 25-66% of a complexing agent and 8-65% of solvent; the preparation method of the zinc oxide ink for printed electronics includes the steps that the chelating agent or the complexing agent is dissolved in the solvent and evenly mixed, then the zinc precursor is added to the mixed liquid and stirred to be dissolved, and the zinc oxide ink for printed electronics can be obtained after filtering; the use method includes the steps that the ink is arranged on a base plate in a printed or coated mode, curing is conducted in air, and a zinc oxide film is obtained. The ink is high in stability, the preparation method is simple, easy to operate, the ink is low in cost and free of pollution, multiple printing or coating methods can be adopted, and the zinc oxide ink for printed electronics and the preparation method and use method of the zinc oxide ink have wide application in preparation of zinc oxide lines or films on a flexible substrate, glass and quartz and optoelectronic devices, such as, transparent conducting thin films, flat displays, solar cell transparent electrodes, pressure sensitive elements and gas sensitive elements.

Description

technical field [0001] The invention belongs to the field of ceramic functional inks for printing electronics, in particular to a zinc oxide ink for printing electronics and its preparation method and use method. Background technique [0002] Zinc oxide has a hexagonal wurtzite crystal structure and is a wide-bandgap semiconductor material with a direct bandgap. The bandgap width at room temperature is 3.3eV, and the exciton binding energy is as high as 60meV. ZnO thin film has good transparent conductivity, piezoelectricity, photoelectricity, gas sensitivity, pressure sensitivity and other properties, and is easy to integrate with various semiconductor materials.
