Synthesis and properties of calcium hydroxyapatite/silk fibroin organomineral composites

Synthesis and properties of calcium hydroxyapatite/silk fibroin organomineral composites

The coprecipitation of calcium hydroxyapatite (HA) (Ca 10 (PO 4 ) 6 (OH) 3 ) and silk fibroin (SF) from an aqueous solution in the Ca(NO 3 ) 2 –(NH 4 ) 2 HPO 4 –NH 3 –H 2 O–SF system has been used to synthesize HA/SF organomineral composites based on nanocrystalline HA, containing 2, 5, and 10 wt %...

Zusammenfassung:The coprecipitation of calcium hydroxyapatite (HA) (Ca 10 (PO 4 ) 6 (OH) 3 ) and silk fibroin (SF) from an aqueous solution in the Ca(NO 3 ) 2 –(NH 4 ) 2 HPO 4 –NH 3 –H 2 O–SF system has been used to synthesize HA/SF organomineral composites based on nanocrystalline HA, containing 2, 5, and 10 wt % SF. The synthesis products were characterized by X-ray diffraction, thermogravimetric analysis, infrared spectroscopy, scanning electron microscopy, and electron spectroscopy for chemical analysis.
