A room-temperature environmentally friendly solution process to assemble silver nanowire architectures for flexible transparent electrodes.

In this study, we present a room-temperature environmentally friendly solution process to optimize the performance of the flexible transparent electrodes by co-assembling Ag nanowires and CaCO nanowires, and then etching CaCO nanowires away, leaving Ag nanowire networks with controllable optical transparency and electrical conductivity. The obtained Ag nanowire flexible transparent electrodes exhibit an averaged transmittance of up to 90% when the sheet resistance is 70 Ω sq which shows no degradation even after 2000 cycles of fatigue test, indicating their excellent mechanical flexibility and stability.
