首次采用溶胶凝胶法结合通孔阳极氧化铝模板, 成功制备出了钛酸锶钡纳米管. 该制备工艺简单、易实现而且成本低. 首先制备通孔阳极氧化铝模板和钛酸锶钡溶胶, 然后通过浸渍加上匀胶的方法将钛酸锶钡溶胶引入到通孔阳极氧化铝模板的纳米孔洞中, 最后在650℃下煅烧1 h形成钛酸锶钡纳米管. X射线衍射(XRD)证明, 制得的钛酸锶钡纳米管为立方钙钛矿相, 主要沿(110)晶向生长. 扫描电子显微镜(SEM)显示, 钛酸锶钡纳米管外径、内径和管长分别为75 nm, 50 nm, 16 μm. 傅里叶变换显微红外光谱仪(FTIR)测试结果表明在波数为1350-1650 cm-1红外波段, 阳极氧化铝/钛酸锶钡纳米管复合结构较钛酸锶钡薄膜有两处明显的吸收峰, 吸收峰位于1470和1550 cm-1处, 与通孔阳极氧化铝模板相比其吸收峰强度高出一倍, 最后分析了出现这一现象的可能原因.Ba0.6Sr0.4TiO3 (BST) nanotubes are fabricated successfully by sol-sel method with the through-hole anodic aluminum oxide (AAO) template for the first time so far as we know. This fabrication method is easy to realize at low cost because the through-hole AAO template and the BST sol can be acquired easily at low cost, so this is very valuable in the fabrication of other similar nanostructures. First, the steady BST sol is prepared and the well aligned through-hole anodic aluminum oxide template is fabricated by a two-step anodization method; second, the BST sol is introduced into the ordered nanohole arrays of the through-hole AAO template by dipping and spinning; and finally, the samples are fired in air at 650℃ for 1 h to get BST nanotubes. X ray diffraction (XRD) patterns reveal that the BST nanotubes are of cubic perovskite structures, and grow mainly along [110] crystal orientation. Scanning electron microscope (SEM) results show that the thickness and pore size of the through-hole AAO template are about 16 μm and 75 nm, respectively. The length, external and inner diameters of the BST nanotubes are about 16 μm, 75 nm and 50 nm, respectively. Measurements of BST nanotubes give results highly matched with that of the through-hole AAO template. Fourier transform infrared spectroscopy (FTIR) results shows that in the 1350-1650 cm-1 waveband, the composite structure of AAO/BST nanotubes has two obvious absorption peaks which are respectively at 1470 and 1550 cm-1, while the BST film does not have; the absorption property of the composite structure is about two times of the pure through-hole AAO membrane. Finally, the possible reasons of this phenomenon about infrared absorption are discussed.
