Abstract:SummaryWe developed the conductive ink using silver (Ag) -copper (Cu) solid solution powder and investigated an ionic migration phenomenon of the conductive ink. The conductive ink is made by dispersing the powder in phenol resin. This powder has a shell structure. The Ag concentration at the surface of the powder is higher than an average Ag concentration in the bulk, and Ag concentration decreases toward inside of the powder. The Ag concentration of about 85 wt% in the Ag-rich phase dose not strongly depend … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
