Screen Printing Silver Stretchable Conductive Paste To High Density Synthetic Fabric, Allison Rose Tuuri, Wesley Graham Powell

Materials Engineering

This project investigated the viability of screen printing stretchable silver conductive paste directly onto fabric and how the resistance changed under cyclic mechanical loading. The paste tested was DuPont™ PE873 stretchable silver conductive paste, which forms a stretchable conductive path by suspending silver flakes in elastomer that can be elastically strained along with the underlying substrate. The silver pastes were printed directly onto two different high-density synthetic fabrics of different weaves. Other samples were prepared by first printing a base layer between the silver paste and the fabric. One base layer was a solvent-based dielectric (DuPont™ ME776) and a stretchable …
