摘要
目的分析一种表面置换的珊瑚羟基磷灰石(SCHA)结构特征,寻找理想的骨修复材料。方法海南天然滨珊瑚在特定温度和压力下部分水热反应,用扫描电镜(scanning electronic microscopy,SEM)、X射线色散谱(energy dispersive X-ray spectroscopy,EDX)、热失重分析(thermo gravimetric analyzer,TGA)的方法表征,分析SCHA孔径大小、计算羟基磷灰石和碳酸钙的成分比例。结果SCHA表面为羟基磷灰石,里面为碳酸钙,保留原有的珊瑚贯穿多孔的三维结构,孔径大小为100～300μm。羟基磷灰石的比例为9.7%,厚度为30μm。结论表面置换的珊瑚羟基磷灰石具有理想的贯穿多孔三维结构,是一种良好的骨组织工程支架材料。
Objective To analyze the structure and characterization of a sort of surface exchanging coralline hydroxyapatite(SCHA).To search for the perfect bone repairing biomaterials.MethodThe Hainan coralline was treated into surface exchanging coralline hydroxyapatite(SCHA) by 'Hydrothermal exchange' at specific condition.The structure and chemical composition of the materials were characterized by scanning electronic microscopy(SEM), energy dispersive X-ray spectroscopy(EDX) and thermo gravimetric analyzer(TGA).Th...
