| 摘要: 采用电化学阳极氧化的方法，以氯化铵(NH4Cl)水溶液为电解液，在纯钛表面制备了二氧化钛(TiO2)纳米管。考察了制备电压、氧化时间、Cl-浓度和钛基体的退火处理对阳极氧化过程的影响规律,探讨了在含氯离子电解液中纳米管的形成机理，并基于上述含氯离子电解液中纳米管形成机制，通过两步阳极氧化法得到无支撑纳米管薄膜。 |

| Abstract: TiO2 nanotubes on titanium substrate were fabricated via electrochemical anodization in NH4Cl aqueous solution. The influence of anodization voltage, chloride ion concentration and annealing treatment of Ti substrate on titanium oxide nanotubes formation was investigated. Formation mechanism of TiO2 nanotubes in chloride containing electrolyte was discussed. Freestanding nanotubes membrane was fabricated via two-step anodization on the basis of the formation mechanism in chloride containing electrolyte. |
| Keywords: nanotube TiO2 chloride ion anodization |
