چکیده مقاله:
Well-dispersed hydroxyapatite nano-rods with different morphologies were synthesized by hydrothermal method in oleic acid/ethanol/water as a reaction system. Surfactants assisted modification effects were investigated. The structure and morphology of synthesized samples were characterized using X-ray diffraction and scanning electron microscopy systems, respectively. The effect of reaction systems and surfactants additives on the morphology evolution of hydroxyapatite nano-rods were discussed. The results show that controlling of reaction conditions, such as content ratio of oleic acid/ethanol, has significant effect on the morphology evolution of the prepared hydroxyapatite nano-rods. Further, the selected surfactants additives, such as cetyltriethyl-ammonium bromide (CTAB as a cationic surfactant) and sodium dodecyl sulfate (K12 as an anionic surfactant) play an important role in formation of uniform morphology of hydroxyapatite nano-rods.
