中文摘要：

采用水热合成法制备钛酸钠纳米管，然后依次与HNO3，正四丁基氢氧化铵水溶液（TBAOH）离子交换后，经过高速离心，将所得沉淀物分散于无水乙醇溶液中，并应用电泳沉积的方法成功地在不锈钢或导电玻璃表面构筑了钛酸纳米管薄膜。采用TEM、XRD、SEM及EDS等对纳米管薄膜的表面形貌、结构和组成等进行表征。结果表明，电泳沉积法制备钛酸纳米管薄膜致密均匀、厚度可控并与基体结合力良好；经高温烧结后，形貌基本保持不变，可望成为一种新的功能材料。文中还对纳米管薄膜的形成机理进行了讨论。

英文摘要：

Titanate nanotubes were prepared by hydrothermal method, then the as-prepared titanate nanotubes exchanged Na^＋ with H^＋ in HNO3 and TBAOH solution in turn. The final product was subsequently suspended in alcoho. The H2Ti3O7 nanotube film was farbricated on a conductive substrate by electrophoresis deposion. The products were characterized by means of transmission electron microscope （TEM）, high-resolution transmission electron microscopy （HRTEM）, scanning electron microscopy （SEM） and X-ray diffraction （XRD）. The as-prepared H2Ti3O7 nanotube film with controllable in thickness is dense and uniform. The morphologies and hydrophilic properties remain unchangeable under the high temperature calcinations, and it is possible to be a new kind of functional material.
