Stretchable and transparent electrodesbased on patterned silver nanowires by laser-induced forward transfer for non-contacted printing techniques
article
Silver nanowires(AgNWs)are excellent candidate electrode materials in next-generationwearable devices due to their highflexibility and high conductivity. In particular, patterningtechniques for AgNWs electrode manufacture are very important in the roll-to-roll printingprocess to achieve high throughput and special performance production. It is also essential torealize a non-contact mode patterning for devices in order to keep the pre-patterned componentsaway from mechanical damages. Here, we report a successful non-contact patterning of AgNWs-based stretchable and transparent electrodes by laser-induced forward transfer(LIFT)technique.The technique was used to fabricate a 100% stretchable electrode with a width of 200μm andelectrical resistivity 10−4Ωcm. Experiments conducted integrating the stretchable electrode onrubber substrate in which LED was pre-fabricated showed designflexibility resulting from non-contact printing. Further, a patterned transparent electrode showed over 80% in opticaltransmittance and less than 100Ωsq−1in sheet resistance by the optimized LIFT technique.
