Hybrid Copper–Silver–Graphene Nanoplatelet Conductive Inks on PDMS for Oxidation Resistance Under Intensive Pulsed Light
A simple,
low-cost, and reliable process of production for conductive tracks
and their transfer to polyÂ(dimethylsiloxane) (PDMS) substrate has
been proposed. Flexible electrodes were fabricated using conductive nanoparticulates under intensive
pulsed light, which were then transferred on to a PDMS substrate via
a pouring, curing, and peeling process. The combination of copper–silver
nitrate–graphene nanoplatelets (GnPs) provided multiple benefits
to the conductive tracks, such as oxidation resistance and increased
durability on PDMS. The addition of silver nitrate reduced the speed
of oxidation during the curing process of PDMS in the presence of
heat and air. The addition of GnPs then increased the stability of
conductive tracks on PDMS, whereas the films without GnPs were not
conductive on PDMS due to mechanical cracks. The copper–silver–GnP
electrodes on PDMS were successfully demonstrated as flexible electrodes
and reveal the enhancement of oxidation resistance during thermal
oxidation for Joule heater application
