Hydroxyapatite (HAp) has been widely used as biomaterials (bone replacement, implant, etc.) thanks to its good biocompatibility. In this study, hydroxyapatite/chitosan (Hap/CS) nanocompozite was prepared by precipitation method. HAp was synthesized from CaCl2 and Na2HPO4 solutions, the interaction between HAp and CS led to the formation of nanosized spindle type HAp particles (long axis is , short axis is ca. 22nm). Then, the obtained nanocompozites were characterized by different physico-chemical analyses (XRD, IR, TEM, TG).
