| 摘 要： | 以含有NH4F的乙二醇溶液为电解液,在宽温度范围内(10~70℃)对纯Ti表面进行阳极氧化,制得形貌可控的TiO2纳米结构。利用场发射扫描电子显微镜(FESEM)和透射电镜(TEM)对纳米TiO2的形貌进行表征。结果表明,随着电解液温度的变化,纳米TiO2的形貌得到控制,可形成TiO2纳米管阵列及纳米管阵列/纳米线复合结构,温度40~50℃为转折温区。 |
| 关 键 词： | 阳极氧化 TiO2纳米管阵列 TiO2纳米线 复合结构 |

| Abstract: | Morphology controllable TiO2 nanostructures were fabricated on the Ti substrate in an ethylene glycol solution of 0.25wt% NH4F via anodic oxidation method at different temperatures(10~70 ℃).The morphology of TiO2 films were studied by field emission scanning electron microscope(FESEM) and transmission electron microscope(TEM).The results show that the morphology of TiO2 nanostructures can be synthesized by temperature control,such as the TiO2 nanotube array or nanotube/nanowire composite film.Temperature between 40 and 50 ℃ is the turning area of changing nanotube to nanowire. |
| Keywords: | anodic oxidation TiO2 nanotube arrays TiO2 nanowire composite structures |
