密度可控钛纳米棒阵列的制备及其矿化性能研究
RARE METAL MATERIALS AND ENGINEERING（2015）
Abstract
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.
