【 摘 要 】

Different nanocrystals of hydroxyapatite-[HAp]-gelatin [GEL], HAp/GEL/Glutaraldehyde (GA), HAp/GEL/Zn and HAp/GEL/GA/Zn were prepared using the biomimetic process. The nanocrystals were characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffraction analysis (XRD). The FT-IR spectra of HAp/GEL nanocrystal materials are similar to the spectrum of real bone. Nanocrystals show (002), (222), (211), and (112) planes, which confirm formation of hydroxyapatite phase. Lattice parameters from X-ray diffraction spectra showed that the metal cation was incorporated into the hydroxyapatite structure and has substituted for calcium in the HAp crystal structure and all of the doped HAp formulations were biphasic and crystalline. The hydroxyapatite/gelatin/zinc (HAp/GEL/Zn) composite sintered in 900°C demonstrated that the c-axes of HAp nanocrystals were regularly aligned along collagen fibers.
