Mg-doped fluorapatite nanoparticles-poly(ε-caprolactone) electrospun nanocomposite: Microstructure and mechanical properties

• We synthesized poly (ε-caprolactone)/Mg-doped fluorapatite nanoparticles (PCL/nMg-FA) nanocomposite via electrospining method.
• The optimum values of polymer concentration, applied voltage were 12 wt.% and 25 kV, respectively.
• The nMg-FA particles were homogeneously dispersed in the nanofibers without any agglomeration.
• The PCL/nMg-FA 5 wt.% nanocomposite scaffold revealed the maximum tensile strength (2.34 ± 0.45).

The aim of this study was to prepare and characterize the poly (ε-caprolactone)/Mg-doped fluorapatite nanoparticles (PCL/nMg-FA) nanocomposite electrospun scaffolds. The effect of solvent type on distribution of nanoparticles and mechanical properties of the scaffolds was also investigated. The optimized nanofibrous scaffold was obtained by 5 wt.% nMg-FA while its tensile strength and elastic modules were significantly enhanced compered to PCL scaffolds. It is noteworthy that no surfactant was used in present study. The Mg-FA nanoparticles were homogeneously dispersed in the nanofibers and prepared scaffolds without any agglomeration.
