研究了模拟体液(SBF)中羟基磷灰石(HA)在细菌纤维素(BC)上的仿生沉淀。在仿生矿化之前，BC首先被浸泡在37℃的0.1M CaCl2溶液中进行化学修饰。用扫描电子显微镜(SEM)、能谱仪(EDS)、衰减全反射-傅立叶变换红外光谱(ATR-FTIR)和薄膜X射线衍射仪(XRD)对所制备的HA/BC复合材料进行了表征。结果表明，羟基磷灰石在BC表面均匀析出。此外，晶体为含碳酸盐的磷灰石，微晶尺寸和结晶度均较低。(C)2005 Elsevier B.V.保留所有权利。
In this work, biomimetic precipitation of hydroxyapatite (HA) from simulated body fluid (SBF) on bacterial cellulose (BC) was studied. BC was firstly chemically modified by soaking in 0.1 M CaCl2 solution at 37 degrees C prior to biomimetic mineralization. The resulting HA/BC composites were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy and thin-film X-ray diffractometry (XRD). The results revealed that the HA minerals were homogeneously precipitated on the BC surface. Furthermore, the crystals were carbonate-containing apatites with low crystallite size and crystallinity.
