用含氟的有机溶剂二甲基亚砜(DMSO)作电解液,通过电化学阳极氧化法,在纯钛片表面制得长度达微米级TiO2纳米管阵列.研究了TiO2纳米管阵列形貌和晶相的转变,并通过模拟体液浸泡研究了其生物活性.采用扫描电镜(SEM) 、X射线衍射(XRD)、傅里叶红外(FT-IR)和透射电镜(TEM)分别对纳米管阵列的形貌和物相进行表征.结果表明:在40 V电压下,阳极氧化24 h,可以制得长12 μm,外径170 nm的无定形氧化钛纳米管阵列.300 ℃热处理后,TiO2纳米管表面开始收缩,由无定形向锐钛矿型转变, 温度升到600 ℃时,氧化钛纳米管表面形成较深的沟壑,锐钛矿型开始向金红石型转变,700 ℃热处理后,TiO2纳米管阵列被破坏.生物活性研究表明,具有TiO2纳米管阵列的钛片经热处理后具有良好的生物活性,能在模拟体液浸泡14 d诱导生成厚达13 μm的碳磷灰石层.
