Low-Temperature Processible Highly Conducting Pastes for Printed Electronics Applications

Scalable additive manufacturing of printed electronics is a growing field accompanied by increasing demands for reliable and integrable functional flexible printed electronic devices. Herein, a novel type of electrically conducting silver-based pastes for additive manufacturing is demonstrated. These pastes are designed for stencil- and screen-printing and can be post-processed at very low temperatures, at ambient. Furthermore, printed lines made with the pastes exhibit an electrical sheet resistance below 60 m omega sq(-1) even after room temperature and only 25 m omega sq(-1) after two minutes of curing at 90 degrees C.
