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

The aim of this study was to prepare and characterize the poly (epsilon-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.
