Notes:
The cylindrical chitosan (CS)/hydroxyapatite (HA) nanocomposites werehydrothermally prepared via in situ precipitation and characterized by x-ray diffractometer(XRD), Fourier transform infrared spectrometer (FT-IR), thermogravimetry (TG) and scanningelectronic microscope (SEM). The results show that the as-prepared products are composed of CSand low-crystalline HA phases, and some extent of interaction between CS and HA phases existsin the composites, which is greatly influenced by the temperature and pH value in thehydrothermal process. The crystal size of HA uniform-distributed in CS matrix is calculated to beno larger than 100nm while the crystallinity of CA is greatly increased in the hydrothermalprocess, which is beneficial to the mechanical properties of the composites. It is proposed that thenano-structure of HA/CS composite will have the better biomedical properties in the biomaterialsapplications
