Transparent ZnO nanorod (NR) films that exhibit extreme wetting states (either superhydrophilicity or superhydrophobicity through surface chemical modification), high transmittance, UV protection and antireflection have been prepared via the facile ammonia hydrothermal method. The periodic 1D ZnO NR arrays showed extreme wetting states as well as antireflection properties due to their unique surface structure and prevented the UVA region from penetrating the substrate due to the unique material property of ZnO. Because of the simple, time-efficient and low temperature preparation process, ZnO NR films with useful functionalities are promising for fabrication of highly light transmissive, antireflective, UV protective, antifogging and self-cleaning optical materials to be used for optical devices and photovoltaic energy devices.
通过简单的氨水电热法制备了具有极端润湿性（通过表面化学修饰表现为超亲水性或超疏水性）、高透光率、紫外线防护和抗反射性能的透明 ZnO 纳米棒（NR）薄膜。周期性的 1D ZnO NR 阵列由于其独特的表面结构和 ZnO 独特的材料性质，表现出极端的润湿性和抗反射性能，阻止 UVA 区域穿透基底。由于制备过程简单、高效且温度低，具有有用功能的 ZnO NR 薄膜有望用于制造高透光率、抗反射、防紫外线、防雾和自清洁的光学材料，用于光学器件和光伏能源器件。
