摘要

采用胶束模板-水热法制备了具有良好热稳定性和生物相容性的羟基磷灰石纳米棒。在150℃下对CTAB/环己烷/乙醇/水相组成的新型胶束前驱体进行了水热处理。XRD和FTIR谱图表明,合成产物具有羟基磷灰石(HA)的结构和主要振动模式。TEM图像显示产物呈细长棒状。模拟体液浸渍的生物矿化结果表明,在浸渍21 d后,羟基磷灰石表面完全被磷灰石层覆盖。

Hydrothermal synthesis and bio-mineralization of hydroxyapatite nanorod
A facile micelle template-hydrothermal method was used to synthesize hydroxyapatite nanorods with good thermal stability and biocompatibility. A novel micelle precursor consisting of CTAB/cyclohexane/ethanol/aqueous phase was hydrothermally treated at 150°C. XRD patterns and FTIR spectra showed that the synthesized products display the structure and main vibration modes of hydroxyapatite (HA). TEM images showed that the products exhibit elongated rod morphology. Bio-mineralization in simulated body fluid (SBF) immersion indicated that the surface of sintered HA is entirely covered with the apatite layer after 21 days immersion.
