摘要 以阳极氧化制备的TiO2纳米管薄膜为模版,通过水热法制备了Ba1-xCexTiO3(0≤x≤0.08)纳米管薄膜,研究了Ba1-xCexTiO3的结构、表面形貌及其电性能。采用X射线衍射仪表征其晶体结构,采用扫描电子显微镜和透射电子显微镜观察其表面及断口形貌,采用宽频介电阻抗谱仪测试其介电性能。结果表明,在较为温和的条件下用水热法成功制备出立方相结构的Ba1-xCexTiO3纳米管薄膜,纳米管孔径在80~95 nm之间;将制备的Ba1-xCexTiO3经退火后生成多晶的Ba1-xCexTiO3纳米管薄膜,且样品的管外径尺寸在90~100 nm之间,管壁的厚度为25~30 nm,介电常数在1 kHz下最高可达472,介电损耗为0.41。

Abstract: Ba1-xCexTiO3(0≤x≤0.08) nanotube thin films were prepared via hydrothermal method, anodized TiO2 nanotube thin films as template. The structure, morphology and electrical properties of Ba1-xCexTiO3 nanotube thin films were investigated. The crystal structure was characterized by X-ray diffraction, the surface and fracture morphology was observed by scanning electron microscopy and transmission electron microscopy, and the dielectric properties were tested by broadband dielectric spectrometer. The result revealed that the Ba1-xCexTiO3 nanotube thin films diameter was between 80—95 nm with cubic phase which were prepared by hydrothermal method under mild conditions. The polycrystalline Ba1-xCexTiO3 nanotube thin film was formed after annealing, and the outer diameter of the tube was between 90—100 nm and the thickness of the tube wall was 25—30 nm, the dielectric constant of thin film in 1 kHz was 472, the dielectric loss was 0.41.
