Electrochemical anodization of a titanium film on a Kapton HN substrate leads to the formation of closely packed aligned nanotubes, whose shape can be finely tuned by tailoring the anodization parameters. An amorphous-to-anatase phase transition is induced on nanotubes by annealing at 350 °C. The nanotubes are applied as photoanodes in flexible dye-sensitized solar cells (N719 dye; I3-/I- redox couple), resulting in a photoconversion efficiency of up to 3.5% under simulated sunlight irradiation air mass 1.5 global (AM 1.5G).
在 Kapton HN 基底上电化学阳极氧化钛薄膜会导致紧密排列的纳米管的形成，通过调整阳极氧化参数可以精细调整纳米管的形状。在 350°C 退火时，纳米管会发生非晶相向锐钛矿相的转变。将纳米管用作柔性染料敏化太阳能电池（N719 染料；I3-/I-氧化还原对）的光阳极，在模拟太阳光照射下（空气质量 1.5 全球，AM 1.5G），光电转换效率高达 3.5%。
