主　　题：Biomaterial hydroxyapatite surface modification 

摘      要：Surface modification of hydroxyapatite(HA)powder was performedwith r-aminopropyl silane in toluent solvent. The modificationeffects were characterized by using XPS and FT-IR methods. Theresults indi- cated that the P2p electron binding energy of themodified HA decrease 0.4 eV compared to that of HA. Further- more, anew peak, 998 cm^-1 absorption appeared in IR differential spectra ofmodified HA and HA, which is due to a stretching vibration ofstructure P-O-Si, meaning that a direct covalent bonding betweenhydroxyl group on HA surface and the organic silane molecule wasrealized after modification, and the chemical bonding type was P-O-Si.
