Hydroxyapatite(HAp) ceramics have the highest biocompatibility to the living tissue of bioactive ceramics. However, their weak mechanical properties limit the applications for implant materials. Thus, in this paper, HAp is reinforced by polyurethane, which has excellent mechanical properties, such as flexibility, in order to overcome the weak points of HAp. The innovative polyurethane/hydroxyapatite nano-composites were developed and their tensile test results showed that the developed polyurethane/hydroxyapatite nano-composites have enough ductile property. Furthermore, it is confirmed that the bioactivity of the developed materials in SBF liquid (simulated body fluid) is excellent.
