Electrospun Nanostructured Fibers of Collagen-Biomimetic Apatite on Titanium Alloy
Figure 1
Scheme of the processing steps involved in the electrospun nanostructured collagen-hydroxyapatite fibers preparation: (a) electrospinning of collagen in CH3COOH solution into an aqueous calcium and phosphate precursor solutions (Ca(CH3COO)2 and NH4H2PO4, resp.) at pH 3; (b) hydrolysis with NaOH to pH 9; (c) aging the composite in reaction mixture for 15 min, followed by harvesting and vacuum drying.
