| 제목 | Reduced Graphene Oxide Wrapped Metal Alloy Nanowires toward Flexible Transparent Conductive Electrodes with Long-Term Stability |
| 초록 | Transparent conductive electrodes (TCE) are widely utilized in optoelectronic devices. The commercial material for TCEs is indium-tin-oxide (ITO), but it has critical drawbacks: brittleness, scarcity of indium resources, a high-cost low-throughput process of ITO deposition. In this respect, copper nanowires (CuNWs) are proposed as excellent alternatives since Cu is less expensive and more abundant, compared to indium. Moreover, they are solution-processible with the possibility of flexible device application. To overcome the susceptibility to rapid oxidation of CuNWs, we developed highly stable metal alloy NW based TCEs capped with reduced graphene oxide (rGO). CuNWs are covered with Ag nanoparticles by galvanic displacement reaction to prevent Cu surface from oxidation in air. Further, thermal stability and electrical conductivity of Cu-Ag alloy NWs were enhanced by introducing rGO. Finally, we seek the potential of these advanced TCEs in optoelectronic devices. |
