Hydroxyapatite (HAp) nanorods with uniform morphology and controllable size were successfully synthesized by precipitating Ca(NO3)2o4H2O and (NH4)2HPO4 in the presence of cetyltrimethylammonium bromide (CTAB) and polyethylene glycol 400 (PEG 400) as cationic surfactant and non-ionic cosurfactant, respectively, under hydrothermal conditions. The effect of hydrothermal temperature on the composition, morphology and size of HAp particles was studied using X-ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR) and scanning electron microscopy (SEM). Results revealed that the morphology and size of HAp particles can be effectively controlled by the presence of CTAB and PEG surfactants. In addition, the temperature of the hydrothermal treatment plays an important role in controlling the morphology and size of HAp particles. The aspect ratio of rod-like particles increases with the increase in the hydrothermal temperature. Moreover, the crystallinity of HAp powders increases with the increase in the hydrothermal temperature. The template action of CTAB and the co-template action of PEG 400 used to regulate the nucleation and crystal growth are also discussed.
