简介：为了满足透明导电薄膜轻便、可折叠、高分辨率及快速响应的需求,在AZO单层透明导电薄膜研究基础上,尝试在柔性PET衬底上制备AZO/Ag/AZO三层透明导电薄膜。先利用光学薄膜设计软件对膜系进行设计优化,再参照此优化值制备研究不同AZO、Ag层对AZO/Ag/AZO薄膜光电性能的影响。通过合理的实验设计与对比,发现在柔性PET衬底上制备的三层AZO薄膜与在硬质衬底上制备的薄膜光电性能相当,且当三层AZO/Ag/AZO薄膜中AZO层厚度在40-45nm,Ag层厚度8nm时,在可见光波段的透过率高达到92%,电阻率低至4.0×10-（-5）Ω·cm,透明导电薄膜的品质因子最高为12.6×10-（-2）Ω-（-1）。得到的AZO/Ag/AZO三层透明导电薄膜具有与常见的ITO薄膜相比拟的性能。
