Reactive silver ink based on silver acetate complex is a particle-free silver ink that thermally decomposes to silver upon mild heating. It can be inkjet printed; spincoated and patterned using roll-to-roll processes for printing and patterning applications.

General description

Silver is a good conductor and is resistant to oxidation. It is used in printed conductors and printable inks (based on silver nanoparticles). Nanosilver is used as an antibacterial material in filters for air and water purification, in textiles, and for wound treatment. Other large scale applications of nanosilver include metallization of solar cells, thin film electronics, sensors, and catalysts.

The product can be stored at room temperature for several months. However if the user plans on not using the ink for long periods of time; refrigerated storage is recommended for best shelf life.
