Inkjet Printing Of Nano-Silver Conductive Ink On Pet Substrate, Skyler Jiang
Inkjet Printing Of Nano-Silver Conductive Ink On Pet Substrate, Skyler Jiang
Materials Engineering
Printing of conductive ink traditionally uses copper-based ink and was used on high temperature metal substrates due to the high curing and sintering temperature of copper. In this experiment, however, Metalon JS-B25P nano-silver conductive ink was printed using an Epson Stylus C88+ inkjet printer on polyethylene terephthalate (PET) based Novele printing media made for low temperature applications. With silver’s lower sintering temperature, the nano-silver particles in this ink are desired to be able to sinter at a low enough temperature to be used on the PET substrate. The printed ink traces were cured with a temperature-controlled hotplate at 100℃, 120℃, …
Screen Printing Silver Stretchable Conductive Paste To High Density Synthetic Fabric, Allison Rose Tuuri, Wesley Graham Powell
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 …
