原位制备聚己内酯和羟基磷灰石复合材料

Synthesis of HAP Composites by Organic SolGel Process

摘要:

采用溶胶凝胶技术和真空干燥技术,原位制备了聚己內酯(PCL)和羟基磷灰石(HAP)多孔复合材料.对样品进行扫描电镜(SEM)、X射线粉末衍射仪(XRD)和拉曼散射光谱(Raman)表征和分析.结果表明,羟基磷灰石与聚己內酯分子间存在弱氢键作用;当羟基磷灰石在复合材料中的质量分数低于40%时,没有明显的相分离现象出现.

Abstract:

Porous polycaprolactone(PCL)/hydroxyapatite(HAP) composites were synthesized by solgel process and vacuum drying technology.The morphology and component phases in hydroxyapatite (HAP) samples were investigated by scanning electron microscope(SEM),X-ray powder diffractometer(XRD) and laser Raman spectrometry(Raman) methods.The hydrogen bond interactions was found between HAP and PCL components,which decreased the phase separation.When the HAP content was below 40% in weightiness,no obvious phase separation was found in PCL/HAP samples.
