本研究利用水热法在钛金属表面生长出具有取向性的钛酸盐纳米管薄膜。通过SEM和TEM研究了反应产物随反应温度、反应时间和NaOH溶液浓度的变化规律，发现在110-150 °C下，用10 M NaOH溶液处理6-48 h，可形成数百纳米长的纳米管。通过对产物的详细观察，提出了取向钛酸盐纳米管薄膜的一般形成机理。钛酸盐纳米管的整体形成过程可以概括为层状三钛酸盐形成、分裂和卷曲的顺序过程。
In this study, oriented titanate nanotubes thin films grow on titanium metal surface via a hydrothermal surface treatment process. A combined SEM and TEM investigation of the reaction products as the functions of reaction temperature, duration and concentration of NaOH solution reveal that several hundreds nanometer long nanotubes are formed by using 10 M NaOH at 110–150 °C for 6–48 h. A general formation mechanism of oriented titanate nanotube thin film was proposed in terms of the detailed observation of the products. The overall formation of titanate nanotubes can be summarized, as a sequence of layered trititanate formation, splitting and scrolling process.
