High performance flexible transparent electrodes based on random networks of copper nanowires are reported. The crucial importance of chemical cleaning of copper nanowires with glacial acetic acid after the hydrothermal synthesis is revealed, giving access to transparent conductive films with excellent performances, typically 55 次/sq. at 94% transmittance, without any need for post-treatment. Encapsulation of Cu nanowire networks with PEDOT:PSS also provides an efficient route to very good transparent electrodes. Furthermore integration of these electrodes into flexible touch sensors is reported.
