Silver-containing electrically-conductive compositions

Abstract

An electrically-conductive composition essentially has (a) an electrically-conductive material consisting essentially of silver nanoparticles that have a d50 of less than or equal to 60 μm and a d90 of less than or equal to 500 μm; (b) particles having a Young's modulus that is different from the Young's modulus of the (a) electrically-conductive material by at least 10%, which (b) particles have a d50 of 500 nm to 300 μm and a polydispersity coefficient of less than or equal to 3; (c) a binder material that is non-electrically-conductive; and (d) a solvent medium in an amount of less than or equal to 90 weight %, based on the total composition weight, which solvent medium is at least 50 weight % water. The weight ratio of the (b) particles to the (a) electrically-conductive material is at least 0.01:1 and up to and including 7:1.
