    Abstract

    The silane coupling agent (KH550) was grafted on the surface of TiO2 nanotubes, and then reacted with high activity-terminated Poly(lactic acid-glycolic acid) (PLGA). The TiO2 nanotubes bonded through the amide bond grafted onto the surface of PLGA. The structure and morphology of the materials were characterized by FTIR, 1H-NMR, TGA, FESEM and TEM methods. The results show that the TiO2 nanotubes are grafted successfully on the surface of PLGA with 18% average grafting. The TiO2 nanotubes/PLGA hybrid scaffolds materials are more conducive for calcium phosphate layers deposition and can improve the surface hydrophilicity.
