| 摘 要： | 采用化学方法处理微弧氧化(MAO)制备的含Si、Ca元素的TiO2涂层(SC), 获得钛氢氧钠(Na0.8H1.2Ti3O7)生物活性纳米线结构。化学处理过程中, SC涂料表面出现了Ca、Na元素溶解, Si元素沉积的现象。化学处理后的SC涂层比SC涂料具有更好的吸水性和诱导磷灰石形成能力。这与处理后涂层(SHTO)特殊的纳米结构有关, 在模拟体液浸泡过程中更容易形成Ti-OH。同时, 钠氢氧钛纳米线的表面形貌、相组成、OH基团以及良好的湿润能力使其更加适合于MC3T3-E1细胞的粘附和增值。

| Abstract: | The bioactive nanowire of sodium hydrogen titanium oxide (Na0.8H1.2Ti3O7) was obtained by Chemical treating the surface of TiO2-based coating containing Si and Ca (SC) prepared by microarc oxidation (MAO). During the chemical treatment, the dissolution of Ca and Si, and the deposition of Na appear on the surface of the SC coating. The chemically treated SC coating shows better hydrophilic and apatite-formation ability than those of the SC coating, which could be associated with the special structure such as OH group in the sodium hydrogen titanium oxide (SHTO) as well as the Ti-OH group formation during the simulated body fluid immersion. At the same time, the SHTO nanowire is more suitable for the MC3T3-E1 cell adhesion and proliferation due to surface morphology, phase composition, OH group structure and better wetting ability. |
