摘要

将金红石型TiO2纳米粉体浸泡在模拟体液中, 于37℃经过不同时间, 制备出磷灰石包覆金红石型TiO2纳米粉体. 用XRD、SEM、TEM、EDX、FTIR、ICPAES和BET方法对复合粉体进行了表征, XRD结果表明,磷灰石的含量可随着金红石型TiO2在模拟体液中浸泡时间的延长而增加. FTIR结果中显示了磷灰石的O-H和PO43-吸收峰, 说明复合粉体中有磷灰石存在. ICP-AES结果表明溶液中Ca和P浓度随浸泡时间延长而下降, 表明时间延长后更多的Ca和P被消耗. TEM和EDX结果证明了金红石型TiO2表面有磷灰石存在, HRTEM结果显示磷灰石(211)面的晶格间距为0.27nm, 晶粒尺寸约为40nm.

Abstract

The composite of nanocrystalline apatite coated rutile TiO2 was prepared by soaking TiO2 nanosized powders into the simulated body fluid (SBF) at 37℃ for the different duration times. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), highresolution transmission electron microscope (HRTEM), energy dispersive X-ray (EDX), fourier transform infrared (FTIR) spectroscope, inductively coupled plasma atomic emission spectrometer (ICP-AES) and N2 adsorption measurements. XRD result shows that the content of the apatite coated on the rutile TiO2 increases with prolonging the soaking time in the SBF. It is demonstrated that composite powders have included some apatite through the absorption peaks of the O-H and PO43-of the apatite in the FTIR spectrum. ICP-AES result shows that Ca and P concentrations decrease with prolonging the soaking time in SBF. It is evident from the TEM and EDX that there is some apatite coated on the surfaces of the rutile TiO2. HRTEM result indicates that the interplanar spacing of (211) of the apatite is 0.27nm and the diameter of apatite nanoparticles is about 40nm.
