Near-room temperature sintering of inkjet printed silver patterns

Abstract

Inkjet printing is a fast, cheap and flexible method to deposit thin and structured layers. In this work precursor based Ag inks were developed instead of the commercially available particle based ones that usually have to be sintered at temperatures of at least 200 °C. It is proven that inkjet printed Ag layers can be sintered at temperatures as low as 60 °C reaching a resistance of less than 5 Ohms/cm with these home-made precursor inks.
