采用阳极氧化法在乙二醇体系电解液中制备TiO2纳米管阵列，获得了长度为15~20μm的底端纳米管与顶端纳米线的新型复合结构。讨论了电解液中不同含水量对该复合结构形成的影响，并采用两步阳极氧化法对该结构的形成机理进行了分析。结果表明，当乙二醇体系电解液含有0.4%(质量分数)NH4 F和2%(体积分数)H2 O 时，电解液腐蚀速度适中，纳米管上端部分被选择性腐蚀，最终形成纳米管与纳米线的复合结构。

TiO2 nanotube arrays were fabricated by anodization in the system of glycol electrolyte.The new composite structure of the bottom nanotube and upper nanowire with the length of 15-20μm were prepared.The influences of the water contents in the electrolyte with respect to the composite structure was studied by two-step anodization.The results show that the composite structure can be obtained according to moderate etching rate of electrolyte and selective etching of the nanotube,when the glycol system electrolyte containing 0.4wt%NH4 F and 2vol% H2 O.
