通过在FTO玻璃上溅射AZO层、对AZO/FTO膜进行热退火以及使用锌箔作为锌源在70 ℃下在退火的AZO/FTO膜上水热生长ZnO纳米棒来制备ZnO纳米棒涂覆的FTO膜。另外两个ZnO纳米棒涂覆FTO薄膜也通过水热生长的ZnO纳米棒上的FTO玻璃和未退火的AZO/FTO薄膜分别用于比较的目的。采用X射线衍射、扫描电子显微镜、水接触/滑动角测量、分光光度法和四探针测量等方法对结果进行了详细的观察。退火AZO/FTO薄膜上的ZnO纳米棒比FTO玻璃和未退火AZO/FTO薄膜上的ZnO纳米棒具有更致密的分布和更好的取向性。结果表明，ZnO纳米棒包覆的退火AZO/FTO薄膜在可见光范围内表现出超疏水性、高透明性和低反射率。此外，该膜具有4.0 Ω/sq的最低薄层电阻，这意味着其良好的导电性。该研究为开发多功能透明导电薄膜提供了有价值的参考。(C)2016年爱思唯尔B。V.保留所有权利。
A ZnO nanorod-coated FTO film was prepared by sputtering an AZO layer on FTO glass, thermal annealing of the AZO/FTO film, and hydrothermal growth of ZnO nanorods at 70 degrees C on the annealed AZO/FTO film using zinc foils as zinc source. Two other ZnO nanorod-coated FTO films were also prepared by hydrothermal growths of ZnO nanorods on the FTO glass and the unannealed AZO/FTO film respectively for comparison purpose. The results were observed in detail using X-ray diffraction, scanning electron microscopy, water contact/sliding angle measurement, spectrophotometry and four-point probe measurement. The ZnO nanorods on the annealed AZO/FTO film were found to exhibit denser distribution and better orientation than those on the FTO glass and the unannealed AZO/FTO film. As a result, the ZnO nanorod-coated annealed AZO/FTO film demonstrated superhydrophobicity, high transparency and low reflectance in the visible range. Also this film had the lowest sheet resistance of 4.0 Omega/sq, implying its good electrical conductivity. This investigation provides a valuable reference for developing multifunctional transparent conductive films. (C) 2016 Elsevier B. V. All rights reserved.
