In situ synthesis and characterization of nano-hydroxyapatite/starch composites

Nano-hydroxyapatite/starch composite was synthesized using in situ precipitation. Starch concentration effect on the structure of composite was examined. Characterization of the obtained samples, The X-ray diffraction and Fourier transform infrared spectroscopy demonstrated the purity of the formed nano-HA in the starch matrix. Morphology studies of the samples, checked by field emission scanning electron microscope and transmission electron microscope, show the effects of starch on the size, shape, and morphology of hydroxyapatite nanoparticles. | Cite this paper Vietnam J.

Keywords. Composite hydroxyapatite starch in situ precipitation. 1. INTRODUCTION engineering. Compared with other polymers this polymer is biodegradable biocompatible and Hydroxyapatite Ca10 PO4 6 OH 2 - HA is an helpful inexpensive. 13 14 In HA starch composites the polar biomaterial with potential orthopedic dental and character of starch providing strong support for maxillofacial applications because of its valuable adhesion between the HA and starch. In this work in biocompatibility bioactivity and osteoconductivity. situ precipitation of HA starch composite starch HA with similarity in chemical and structural concentration effect on the final .
