In this article, the hydroxyapatite and carbonate(HAC) nanoparticles were obtained by calcining the original pig bones, and the influence of different calcining temperature on morphology and size was investigated. Then, the polycaprolactone(PCL)/HAC composite materials were synthesized through in-situ polymerization with caprolactone(CL) and HAC. The effects of different weight ratios of HAC to CL on the performance of composites was discussed, and the morphology and microstructure of obtained composite materials were characterized by transmission electron microscopy(TEM), Fourier transform infrared(FT-IR) and (X-ray diffraction)XRD, etc. The results showed that HAC was uniformly dispersed in PCL matrix, and the composite material with HAC of 6 wt% was chosen for further application. This study provided a new way for synthesizing PCL/HAC materials that could be used for repairing and substituting for human damaged bone, which is significant in the theory and practice of bio-medicine.
