以金属钛板作为阳极材料，采用阳极氧化方法制备了二氧化钛（ TiO2）纳米管，通过X射线衍射仪和扫描电子显微镜等测试，研究了制备工艺条件和超声波源对样品性能的影响．结果表明：纳米管的形貎和结晶性能与工艺参数和超声波源密切相关，退火处理能使样品由不定形相转成由锐钛矿相和金红石相组成的混合相，其生长速度、管径和管壁厚度明显受到阳极氧化时平均电流密度的影响．氧化电压为60 V时所制备TiO2纳米管样品的管径为90 nm、管壁厚度为21 nm、长度为8μm．
以金屬鈦闆作為暘極材料，採用暘極氧化方法製備瞭二氧化鈦（ TiO2）納米管，通過X射線衍射儀和掃描電子顯微鏡等測試，研究瞭製備工藝條件和超聲波源對樣品性能的影響．結果錶明：納米管的形貎和結晶性能與工藝參數和超聲波源密切相關，退火處理能使樣品由不定形相轉成由銳鈦礦相和金紅石相組成的混閤相，其生長速度、管徑和管壁厚度明顯受到暘極氧化時平均電流密度的影響．氧化電壓為60 V時所製備TiO2納米管樣品的管徑為90 nm、管壁厚度為21 nm、長度為8μm．

The titanium oxide ( TiO2 ) nanotubes were prepared by anodization method using the titanium foils as anodes. The characteristics of the prepared samples were investigated by X-ray diffractometer and scanning electron microscopy.The results indicated that the morphology and crystallinity of the samples are closely related to the preparation conditions and ultrasonic wave used.The heat treatment brings about the transform from amorphous structure into anatase and rutile for the TiO2 samples.The growth velocity, diameter and wall thickness of TiO2 nanotubes are subjected to the average current density during anodization.The TiO2 nanotube samples prepared using 40 V anodization voltage have diameter of 90 nm, wall thickness of 21 nm and lengths of 8 μm.
