摘　　要：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。Highly ordered, oriented TiO2 nanotube arrays were fabricated by constant current oxidization. Dense- TiO2 films were prepared by sol-gel dip-coating.Then TNA and Dense-TiO2 were characterized by XRD,RAMAN and FE SEM.Adhesion between Dense-TiO2 and TNA was detected by AFM.Tbe adhesion was heterogeneity was found because of their surface topography heterogeneity. It was further found that the average adhesion between the probe and TNA was 1.65nN,average adhesion between the probe and TNA 20V was 2.39nN, much smaller than dense TiO2 fihn which was 30. 10nN.This may own to their effective contact aera and nanomeler scale roughness.
