Polycaprolactone and hydroxyapatite powders were used as raw materials to prepare polymer threedimensional porous scaffolds by solvent casting/vacuum evaporation/particle leaching (SC/VV/PL). X-ray diffraction (XRD)

scanning electron microscopy (SEM) and infrared analyzer (FT-IR) characterized the composition and microstructure of the scaffold. The related physical and chemical properties of the scaffold were studied. The results show that PCL/HA composite scaffolds with high porosity and good mechanical properties are successfully prepared. The pore size of PCL/HA composite scaffolds is between 100~300μm

the porosity has reached to 83%~89%

which is in line with the requirements of porous scaffolds. The requirements also show that the composite of HA can improve the crystallinity and mechanical strength of the scaffold

and the compressive strength reaches 3.6~5.1MPa.
