| 제목 | Curved Copper Nanowires-based Flexible Transparent Conductive Electrodes by Fully Solution Processes |
| 초록 | Flexible transparent conductive electrodes (FTCEs) based on metal nanowires (NWs) have attracted considerable attention due to their high electrical conductivity and outstanding flexibility. Especially, copper (Cu)-based materials have rich resources and remarkably cheap prices to satisfy the market needs of electronics. However, several technical issues are still blocked the Cu NW-based FTCEs for widespread applications, such as the high surface roughness, the low robustness and the difficulty of patterning. In this work, we reported an all-solution fabrication of the curved copper nanowires (CCNs)-based FTCEs utilizing a combination of self-designed innovative techniques, such as multi-polyol synthetic method, meniscus dragging deposition method, polyurethane (PU)-stamped patterning method, solvent-dipped welding method and PU-embedded transfer method. These suggested methods effectively solved the technical problems of the low-cost fabrication, the low robustness, the high roughness and the difficulty of patterning. As a result, the CCNs thin film partially embedded into PU matrix exhibited excellent opto-electrical performance (Rs = 53.48 Ω/□ at T = 85.71%) and high mechanical stabilities (R/R0 ＜ 1.02 at 1000th bending and R/R0 ＜ 1.10 at 10th tape peeling) with low surface roughness (Rrms = 14.36 nm). |
