Flexible and transparent electrodes imprinted from Au nanowires: stability and ageing
Plasma sintering lines imprinted from oleylamine-capped Au nanowires yields conductors with porous Au shell and hybrid core. Thick conductors retain more organics and age faster than thin ones. PEDOT:PSS coatings stabilize the shell and stop ageing.
