PREPARATION AND THERMAL STUDY OF NANOCOMPOSITES OF HYDROXYAPATITE/BIODEGRADABLE COPOLYESTERS FOR BIOMEDICAL APPLICATIONS

摘要

Novel nanocomposites composed of hydroxyapatite (HAP) and biodegradable copolyesters synthesized via ring-opening copolymerization of succinic anhydride (SA) and glycidol (GA) were developed. They were characterized by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The hydroxyapatite/biodegradable copolyesters nanocomposites were prepared through a solvent-cast technique. This paper describes the preparation and microstructure of the HAP nanocrystals and hydroxyapatite/ biodegradable copolyesters nanocomposites. The results of these studies are described and discussed.
