中文摘要：
通过控制电解液中的草酸含量,在医用纯钛表面构建密度可控的钛纳米棒阵列。利用场发射扫描电镜（FE-SEM）和原子力显微镜（AFM）对钛表面纳米棒阵列形貌和密度进行了表征,并在模拟体液（2SBF）中对其矿化性能进行研究。结果表明：钛纳米棒阵列密度随着草酸含量的增加而增大,钛表面构建纳米棒阵列结构有利于类骨钙磷矿物的沉积,当纯钛表面纳米棒阵列密度为（1.79±0.04）×1010/cm2时,在模拟体液中矿化性能优异,可见这种结构有利于材料与骨组织形成骨性结合,提高临床疗效。
英文摘要：
Ti nanorod arrays with controllable density on titanium surfaces were prepared by tuning the content of oxalic acid. The field emission scanning electron microscopy（FE-SEM） and atomic force microscope（AFM） were used to analyze the topography and density of titanium nanorod arrays. Bioactivity was investigated by immersing the samples in a simulated body fluid（2SBF） for 3 and 5 d. Results demonstrate that the different densities of nanorod arrays result from the change of the concentration of H＋. The approach herein can be developed to be a facile nanotechnology for nano-functionalization of titanium. The structure of titanium nanorod arrays promotes the growth of calcium phosphate on the surface of the titanium, the mineralization ability is the best at density of（1.79 ± 0.04）×1010/cm2. By this token, the nanostructure facilitates the osseointegration between the bone tissue and implant, and subsequently improves the performance in clinic.
