Title:
ELECTRICALLY CONDUCTIVE PASTE
Document Type and Number:
WIPO Patent Application WO/2015/005204
Kind Code:
A1
Abstract:
Provided is a superior electrically conductive paste that can be applied or printed, is further able to expand/contract, and moreover can achieve a high-conductivity conductive film. The electrically conductive paste results from a conductive filler (B) being uniformly dispersed in a resin (A), the resin (A) is a rubber (A1) containing sulfur atoms and/or a rubber (A2) containing a nitrile group, the conductive filler (B) is metal particles (B1) having an average particle size of 0.5-10 μm and a conductive material (B2) having, at the surface, a group selected from a mercapto group, an amino group, and a nitrile group, and an aspect ratio of 10-10,000. The conductive filler (B) may be surface-treated by means of a rubber containing a sulfide bond and/or a nitrile group instead of having the aforementioned groups at the surface. Also, the conductive filler (B) may be a metal nanowire.
