Room Temperature Electronic Functionalization of Thermally Sensitive Substrates by Inkjet Printing of a Reactive Silver‐Based MOD Ink

The developments in inkjet printing technology and the printed electronics industry past two decades have provided cost-effective, environment-friendly, reliable alternates to traditional methods of fabricating electrical devices. However, most commercial metallic inks require high sintering temperatures form desired functional patterns, which limits applications scenarios that devices on thermally sensitive substrates, like biomaterials or bio-synthetic composite materials. This study has synthetic route a novel silver-based metal organic decomposition (MOD) ink been used highly conductive silver films skin-inspired silk/epoxy substrates by directly with accurate pattern control, whilst self-decomposing at room temperature. fabricated patterns substrate were conductivity 4.65 × 104 S m−1. These also showed impressive malleability as bulk films, could be further developed into motion sensors for wearable medical applications. Our strategy provides general platform electronic functionalization without temperature constraints. particle-free, reactive silver-precursor, lower widen choices exemplified herein outstanding quality (1.20 106 m−1) achieved paper.
