摘　　要：羊蜡酸作为一种典型的有机脂肪酸,因具有良好的生物键合能力而受到医学界的广泛关注.本文作者在醇/水混合溶剂中,通过羊蜡酸插层制备了介观层状羟基磷灰石,并采用红外光谱、X射线衍射以及透射电镜进行了相应的表征.分析结果显示,羊蜡酸在形成层状介观结构中起着重要的作用,所制备的样品层间距约为3.1nm,羊蜡酸层与羟基磷灰石层呈现交替叠加的层状结构.As a typical organic fatty acid,capric acid has been widely concerned in the medical community because of its good biological bonding ability.In this paper,mesoscopic lamellar hydroxyapatite（ML-HA）was prepared by capric acid intercalation.The products were characterized by infrared spectroscopy,X-ray diffraction and transmission electron microscopy.The analysis results reveal that capric acid played a decisive role in the formation of lamellar mesostructures.The lamellar spacing of the sample is about 3.1nm with the layered structure of capric acid layer and hydroxyapatite layer alternately superimposed.
