通过水热法,在FTO导电玻璃表面合成了TiO_2纳米棒簇及气孔双重修饰的TiO_2单晶纳米棒阵列薄膜,其中纳米棒簇由水热溶液中TiO_2晶核在薄膜表面的沉积生长而形成,气孔则通过聚苯乙烯(PS)微球模板形成。利用扫描电子显微镜(SEM)及X-射线衍射仪(XRD)对所合成的薄膜进行了表征,利用水接触角的测试评价了薄膜表面的水润湿性能。结果表明,纳米棒簇及直径1μm以下气孔的修饰能显著提高TiO_2纳米棒阵列薄膜的疏水性能,测试的水接触角达到100~130°,与未修饰的纳米棒薄膜相比,接触角增大了约1倍。
TiO 2 nanorods clusters and double modified TiO 2 single crystal nanorod array films were synthesized on the surface of FTO conductive glass by hydrothermal method. The nanorod clusters were formed by the deposition and growth of TiO 2 nuclei on the surface of the thin films in hydrothermal solution. Stomata are formed by polystyrene (PS) microsphere templates. The synthesized films were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water wettability of the films was evaluated by water contact angle test. The results show that the nanorod clusters and pores with a diameter of 1μm can significantly improve the hydrophobicity of TiO 2 nanorod arrays. The contact angle of water reaches 100 ~ 130 °. Compared with unmodified nanorod films, the contact angle increases About 1 times.
