在本研究中，我们研究了纳米多孔阳极氧化钛基材对水热沉淀羟基磷灰石涂层的形貌和均匀性的影响。纳米管 TiO2 基材通过阳极氧化在钛板上合成，随后在 500 °C 或 600 °C 下退火，形成结晶锐钛矿和/或金红石形式的 TiO2。该底物进一步用于水热条件下的 HAp 生长。然后使用 XRD、拉曼和 SEM 技术对样品进行表征。结果表明，水热合成导致HAp颗粒针状包覆层的形成。 HAp晶体的直径和长度随着TiO2纳米管阵列退火温度的升高而减小。此外，我们证明氧化钛的纳米结构表面对 HAp 成核和覆盖具有有益的影响。
In this study we investigate the effect of the nanoporous anodic titanium oxide substrate on the morphology and uniformity of hydrothermally precipitated hydroxyapatite coatings. Nanotubular TiO2substrates were synthesized on a titanium plate by anodic oxidation and subsequently annealed at 500 °C or 600 °C to create the crystalline anatase and/or rutile forms of TiO2. The substrates were further used for HAp growth under hydrothermal conditions. The samples were then characterized with the XRD, Raman and SEM techniques. The results show that hydrothermal synthesis leads to formation of needle-like coating layer of HAp particles. The diameter and length of HAp crystals decrease with increasing annealing temperature of TiO2nanotubular arrays. Furthermore, we demonstrate that nanostructured surface of titanium oxide has beneficial influence on the HAp nucleation and coverage.
