Abstract

The invention discloses a colorless transparent conductive ink. The ink is prepared from the following raw materials by weight percent: 12%-21% of silver salt, 36%-53% of solvent, 27%-43% of additive and 0.1%-2.1% of dispersant. The ink has the advantages of good spraying property, good reliability, good image quality and good safety and can be used in the common home piezoelectric ink jet printer to prepare an electric circuit; and the common flat-plate printer can be utilized to prepare silver conductive patterns on different substrates. The invention also discloses a preparation method of the colorless transparent conductive ink. The method comprises the following steps: placing the silver salt in the organic solvent, performing ultrasonic vibration for 1-5 minutes; and adding the additive under stirring, stirring for 5-20 minutes, then adding the dispersant, stirring for 5-30 minutes and filtering to obtain the colorless transparent conductive ink. The method has the advantages ofsimple preparation technology, mild reaction conditions, good controllability, short preparation period, low production cost and the like.

Description

technical field [0001] The invention relates to the field of conductive ink and its preparation, in particular to a colorless and transparent conductive ink and its preparation method and application. Background technique [0002] At present, the fabrication of conductive circuits by inkjet printing technology is a relatively popular and important application. In the process of using inkjet printing technology to prepare conductive circuits, the key technology is to prepare conductive ink suitable for inkjet printing. The performance indicators of conductive ink suitable for inkjet printing mainly include: (1) Sprayability: it is expressed as three indicators of ink particle size, viscosity and surface tension. Generally speaking, the particle size in the ink should be less than 1 μm, the viscosity should be 5-35 mPa·S, and the surface tension should be 10-50 mN / m. For different printers, these indicators of ink are also slightly different. (2) Reliability: no clogging of...
