Abstract

The invention relates to a preparation method of a microcircuit, in particular to a method for preparing a microcircuit by printing liquid metal ink through a commercial ink-jet printer and application thereof, and belongs to the technical field of preparation of microcircuits. The liquid metal ink comprises liquid metal, a surfactant and a proper amount of solvent, the weight ratio of the liquid metal to the surfactant is 1: (0.2-0.6), and the preparation method of the liquid metal ink comprises the steps that a mixed solution of the liquid metal, the surfactant and the solvent is subjected to ultrasonic treatment through a probe to be evenly dispersed, the ultrasonic power of the probe is 300-600 W, and the treatment time is 10-60 minutes. The ink has good stability, the particle size of the ink is smaller than that of a nozzle, the viscosity of ink-jet printing is facilitated, and the ink can be used for preparing microcircuits by commercial ink-jet printers.

Description

technical field [0001] The invention relates to a method for preparing a microcircuit, in particular to a method for preparing a microcircuit by printing liquid metal ink with a commercial inkjet printer and its application, and belongs to the technical field of preparation of a microcircuit. Background technique [0002] With the rapid development of society, people's demand for flexible electronic devices that can adapt to various scenarios has greatly increased. However, in traditional electronic equipment, the energy storage system, control system, and functional system usually need external wires to connect, and at the same time cooperate with the soldering process, which not only increases the difficulty of electronic equipment integration, but also makes it difficult for electronic equipment to be flexible and difficult to meet Requirements for multi-scenario use. In recent years, planar flexible devices have attracted great attention and made flexible electronic dev...
