Fast Coprecipitation of Calcium Phosphate Nanoparticles inside Gelatin Nanofibers by Tricoaxial Electrospinning

摘要: We present an effective method for fabricating electrospun gelatin nanofibers containing well-dispersed inorganic nanoparticles. The new encompasses the use of a special triaxial needle where mixing calcium and phosphate aqueous solutions in intermediate yield CaP nanoparticles that immediately after precipitation are dragged by outer polymeric solution incorporated directly electrospinning jet, before nanofiber formation. Gelatin mats different amounts were prepared characterized SEM, TEM, TGA, stress-strain measurements. results demonstrate particles having diameter few tens nanometers successfully introduced during process they well dispersed throughout fiber length. In addition, enabled modulating amount nanofibers.
