Description
Summary:Nano-hydroxyapatite samples with different morphologies were successfully prepared by chemical precipitation method using polyethylene glycol (PEG) as a template. The phase composition, micro-morphology and surface functional groups of the nano-hydroxyapatite samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM), respectively. The results reveal that the mirco-morphology of hydroxyapatite can be effectively controlled by adjusting pH values in the preparation. Moreover, the growth mechanism of HAp with different morphologies was also discussed. •HAp with different morphology was obtained by chemical precipitation method.•HAp morphology can be simply controlled by changing pH value.•PEG inhibited the c-column growth of HAp and thus formed laminated morphology.•Solution environment influenced reaction mode and then changed HAp growth pattern.
