Low temperature wiring with Ag inks: New β-ketocarboxylate Ag inks for 100 °C curing

This paper summarizes a Ag carboxylate ink technology for patterning circuits on heat-sensitive substrates. Low temperature processes for making circuits is becoming one of the key issues for printed electronics primarily because of the potentials of heat-sensitive substrates such as PET films and papers. The authors have developed ß-ketocarboxylate Ag inks that can be cured around 100°C. The electrical specifications and microstructural observations of the new ink printed on commercial papers are demonstrated.
