제목 Photopatternable Silver Nanowire Electrodes for Fabricating Robust OLEDs
초록 We developed a simple fabricating silver nanowire (AgNW) micropatterns on a plastic substrate using a photocurable polymer. The patterning method began with the lamination of a UV–curable prepolymer film onto the AgNW–coated glass substrate. Selective UV exposure through a photomask solidified the exposed regions, and the unexposed regions were removed by the solvent. AgNW micropatterns of various sizes and shapes could be formed across the entire plastic substrate. This photopatterning process enabled the embedding of the AgNW into the polymer matrix, which reduced the surface roughness and enhanced the mechanical stability of the AgNW film. The AgNW structures served as transparent electrodes in organic light–emitting diodes (OLEDs) that performed well compared to OLEDs fabricated using conventional indium tin oxide (ITO) or conducting polymer electrodes. This simple and scalable AgNW patterning technique provides a novel approach to realizing flexible electronics.
