| 摘要: 为制备具有与天然生物骨磷灰石结构相似的羟基磷灰石（hydroxyapatites简称HAP或HA）材料，依据生物矿化的原理，通过以十六烷基三甲基溴化铵（CTAB）作为表面活性剂，正己醇为助表面活性剂，十六烷为油相和水作出的拟三元相图，找到体系所形成的双连续微乳液作为模板，控制矿化材料的成核和生长，并用SEM，TEM，XRD，IR等手段对合成的样品进行了形貌和结构的表征，并将其与共沉淀法制备的HAP在模拟体液中的溶解性进行了比较。结果表明：得到的矿化产物是具有棒状的六方晶体组成羟基磷灰石矿化材料，其结构参数a0=0.920，c0=0.688，与天然生物骨材料较相似，抗体液溶解性比共沉淀法制备的优越。 |

| Abstract: Hydroxyapatites with nature-bone materials’structure were synthesized, based on biomineralization principles by a bicontinuous microemulsion template method. The microemulsion template was made up of CTAB, hexanol, hexadecane and water in molar ratio of 1.00∶1.05∶1.05. The mineralization of materials’nucleation and growth was controlled by this template. The framework and structure were characterized by means of SEM, TEM, XRD and IR. A comparison was made between the samples and the one prepared by co-precipitation on dissolving ability in simulate body fluid. The results show : the products were stick monomer hydroxyapatites and their structure parameter were a0=0.920, c0=0.688, in agreenment with that of the nature-bone materials, and their properties were better than the one made by co-precipitation. |
