A flexible, room-temperature and solution-processible copper nanowire based transparent electrode protected by reduced graphene oxide exhibiting high performance and improved stability.

摘要: Advances in flexible electronic and optoelectronic devices have caused higher requirements for fabricating high-performance low cost transparent conductive electrodes (TCEs). Copper nanowires (Cu NWs) possess excellent electrical optical properties, but the large contact resistance poor stability limit their practical application devices. In this work, we report a robust, convenient environment-friendly method to assemble copper nanowires/reduced graphene oxide NWs/rGO) TCEs with enhanced conductivity, flexibility at room temperature. The NaBH4 treatment was used remove organics oxides on surface of Cu NWs, (GO) capping layer also effectively reduced same time. best NWs/rGO composite show good optical-electrical performance sheet ∼50 Ω/sq transmittance 83% as well superior mechanical flexibility. oxidation NWs normal environment even relatively high temperature has been greatly improved. Additionally, based heaters presented saturation rapid response time under voltage. are expected be applied various types
