EFFECT OF SPRAY DRYING TEMPERATURE ON HYDROXYAPATITE-HYDROXYAPATITECHITOSAN CHITOSAN COMPOSITES

摘要

Hydroxyapatite (HAp) is chemically very similar to the mineralized human bone.Since the scaffold materials made of hydroxyapatite and biodegradable polymers allow good biocompatible harmony with human tissue, the bioactive HAp-polymer composites have an increased interest in recent years.In this study, HAp-chitosan composites was produced by spray drying technique with two different inlet temperature, 120℃ and 160℃.Synthesized HAp-chitosan samples were structurally characterized using FTIR, SEM, XRF, BET and XRD.Particle size measurements were made using ZetaPals.
