采用阳极氧化法制备出规整TiO_2纳米管阵列(TNA),溶胶-凝胶法制备致密TiO_2膜(Dense-TiO_2)。通过采用拉曼光谱(Raman)、X射线衍射(XRD)分析TNA、Dense-TiO_2表面,结果表明均为锐钛矿相,并采用场发射扫描电子显微镜(FE-SEM)、原子力显微镜(AFM)对Dense-TiO_2膜和TNA进行表征,结果表明TNA、Dense-TiO_2膜的粘附力分布呈非均一,粘附力随表面纳米形貌的变化而变化;孔径为9.9nm的TNA-V10的平均粘附力为1.65nN,孔径为35.3nm的TNA-V20的平均粘附力为2.39nN,Dense-TiO_2膜的平均粘附力为30.10nN。TNA的粘附力小于Dense-TiO_2膜的粘附力。
Anatomized TiO 2 nanotube arrays (TNAs) were prepared by anodic oxidation and dense TiO_2 films were prepared by sol-gel method. The surface of TNA and Dense-TiO 2 were analyzed by Raman and XRD. The results showed that all of them were anatase phase, and their structures were characterized by field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) The results showed that the distribution of TNA and Dense-TiO 2 films was inhomogeneous, and the adhesion of TEN-Dense-TiO 2 film changed with the change of surface morphology. The average of TNA-V10 with 9.9 nm pore size The average adhesion of TNA-V20 having an adhesion of 1.65 nN, a diameter of 35.3 nm was 2.39 nN, and the average adhesion of Dense-TiO 2 film was 30.10 nN. The adhesion of TNA is less than the adhesion of Dense-TiO 2 film.
