Among various biomaterials employed for bone repair, composites with good biocompatibility and osteogenic ability had received increasing attention from biomedical applications. In this study, we doped selenium (Se) into hydroxyapatite (Se-HA) by the precipitation method, and prepared different amounts of Se-HA-loaded poly (amino acid)/Se-HA (PAA/Se-HA) composites (0, 10 wt%, 20 wt%, 30 wt%) by in-situ melting polycondensation. The physical and chemical properties of PAA/Se-HA composites were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Differential scanning calorimetry (DSC), Thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM) and their mechanical properties...
