Zhu, A.Lu, Y.Si, Y.Dai, S.2012-01-092012-01-092011Applied Surface Science, 2011; 257(8):3174-31790169-4332http://hdl.handle.net/2440/69151Rod-like hydroxyapatite (HAp) nanoparticles with various aspect ratios are synthesized by means of low-temperature hydrothermal method in the presence of a N-[(2-hydroxy-3-trimethylammonium) propyl]chitosan chloride (HTCC) template. The synthesized HAps were examined by X-ray diffraction (XRD), Fourier transform infrared spectrophotometer (FTIR) and transmission electron microscopy (TEM) techniques. The results reveal that HAps are rod-like monocrystals, where the size and morphology can be tailored by varying synthesis conditions, such as pH, hydrothermal synthesis temperature and the ratio of PO43− to the quaternary ammonium in HTCC. The mechanism of HTCC template on HAp nanorod preparation is analyzed.enCopyright © 2010 Elsevier B.V.
