中文摘要	以阳极氧化法制备的TiO2纳米管阵列为模板,结合水热法制备了钛酸钡纳米管阵列薄膜。研究了水热反应温度、反应时间对BaTiO3纳米管阵列薄膜表观形貌及电学性能的影响。样品经X射线衍射仪表征其晶体结构;扫描电子显微镜观察其微观形貌;以及使用宽频介电阻抗谱仪测试了样品的介电性能。结果表明,在较低的水热温度下即可制得单一立方相的BaTiO3纳米管阵列薄膜,纳米管壁厚约30 nm,薄膜厚度可达10μm;水热反应温度的升高和反应时间的延长有助于样品的结晶度完善和介电性能的提高;未经热处理的薄膜样品在1 KHz介电常数可达200。; Thin films of barium titanate ceramic nano-tubes were prepared via hydrothermal method using TiO2 nanotube arrays by anodized as a template. To discussed that hydrothermal temperature and reaction time effected on morphology and electrical properties of samples. Crystal structure were observed by X-ray diffraction and and micromorphology by scanning electron microscope; dielectric properties of samples were characterized by broadband dielectric spectrometer. The results show that single cubic phase structure of barium titanate nanotube thin films can be obtained under a low temperature, the thickness of tube wall is about 30 nm and the length of the tube is about 10 μm. The higher hydrothermal temperature and the longer reaction time were helpful to enhance the crystallinity and promote the dielectric properties of samples.
