Conductive Inks Based on Metallic Silver Nanoparticles with Enhanced Properties

With the development of science and technology, new approaches have been proposed that can be used in various fields to produce new goods with particular characteristics. Electronic printing is a new technology responsible for producing electronic goods by using a material so-called conductive ink. Nowadays, metal nanoparticles such as gold, silver, and copper nanoparticles have attracted significant attention to be employed in conductive ink. Fillers used in the conductive inks have different properties, among which silver nanoparticles are the most common metal nanoparticles that are utilized to make conductive inks owing to their high conductivity besides their low cost. However, these materials encounter challenges because of their high sintering temperature. In this study, different methods for preparing conductive ink based on silver nanoparticles are pointed out to attain a conductive metal ink with desirable properties.
