In this work, nano hydroxyapatite (nHAp) composites were synthesized via an in situ biomimetic process at room temperature by using gelatin as a template agent. Formation of hydroxyapatite nanoparticles and the effect of biopolymer concentration on the shape and morphology of the nHAp nanoparticles were confirmed and investigated by using X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Scanning and Transmission Electron Microscopy (SEM and TEM). The results indicated that, the gelatin biopolymer as a template agent in the preparation batch has influences the size and morphology of the HAp nanocrystals precipitated in an aqueous solution of gelatin.
在这项工作中，通过在室温下使用明胶作为模板剂的原位仿生过程合成了纳米羟基磷灰石（nHAp）复合材料。通过 X 射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、扫描和透射电子显微镜（SEM 和 TEM）证实并研究了羟基磷灰石纳米粒子的形成以及生物聚合物浓度对 nHAp 纳米粒子形状和形态的影响。结果表明，明胶生物聚合物作为制备批次中的模板剂，影响在明胶水溶液中沉淀的 HAp 纳米晶的尺寸和形态。
