分别采用多元醇法和射频磁控溅射法在玻璃基底上制备了银纳米线（AgNWs）/ZnO：Al（AZO）双层薄膜。研究了AgNWs/AZO双层膜和AZO单层膜的微观结构、光学、电学性能和环境稳定性。AgNW/AZO双层结构在250 °C下退火可以提高其电学性能和环境稳定性。与AZO薄膜的方块电阻24 Ω/sq和方块电阻衰减率102%相比，AgNW/AZO双层膜的方块电阻在湿热30天后下降到9.8 Ω/sq，方块电阻衰减率也下降到20.2%。AgNW在AZO薄膜上的网络分布减轻了晶界的负面影响，这被认为是提高导电性和环境稳定性的原因。
A silver nanowires (AgNWs)/ZnO:Al (AZO) bilayer coating was coated on glass substrates at room temperature by using a polyol method and radio frequency magnetron sputtering, respectively. The microstructure, optical, electrical properties and environmental stability of the AgNWs/AZO bilayer and AZO single layer were investigated. The bilayer structures of AgNWs/AZO annealed at 250 °C could lead to an enhancement of the electrical properties and environmental stability. The sheet resistance of AgNWs/AZO bilayer decreased to 9.8 Ω/sq and the degradation percent of the sheet resistance also decreased to 20.2 % after damp heat testing for 30 days compared to AZO films with the sheet resistance of 24 Ω/sq and degradation percent of the sheet resistance of 102 %. The network distribution of AgNWs on AZO films with the columnar grain structures mitigated the negative effect of grain boundaries, which was considered to be the reason of the improvement in conductivity and environmental stability.
