摘要: Abstract Scaffolds comprising hydroxyapatite (HAP) or poly(ɛ-caprolactone)-grafted (g-HAP) and poly(ɛ-caprolactone) (PCL) were prepared using the thermally induced phase separation/salt leaching technique. The g-HAP nanoparticles evaluated by Fourier Transformation Infrared Spectroscopy (FTIR) thermal gravimetric analysis (TGA). Power X-ray Diffraction (XRD) patterns confirmed successful grafting on surface of HAP. effects mechanical strength, porosity property scaffolds introduction extensively investigated. compressive modulus scaffold was greatly improved addition nanoparticles. Especially g-HAP/PCL containing 20 wt% 59.4% higher than that corresponding HAP/PCL scaffold.
