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

Abstract

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 CaCO₃ nanowires, and then etching CaCO₃ 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⁻¹ which shows no degradation even after 2000 cycles of fatigue test, indicating their excellent mechanical flexibility and stability.
