Magnetic composite structures were fabricated by embedding iron oxide nanoparticles (Fe3O4) into polycaprolactone (PCL) nanofibers through an electrospinning process. The PCL nanofibers incorporating 0.5 and 1 wt. % Fe3O4 were electrospun with various yarn and membrane architectures. SEM images of the fabricated fibers revealed diameter increment by raising the Fe3O4 proportion. Additionally, elongation at break, in tandem with the ultimate strength of the electrospun PCL yarn was improved by 63 and 67% through embedding 0.5 and 1 wt. % Fe3O4, respectively. The saturation magnetization results depended on the number of magnetic nanoparticles loaded in the electrospun fibers, as well as the architectural design of the electrospun fibers. The magnetic response of the fibrous yarns was enhanced by increasing the Fe3O4 mass fraction from 0.5 to 1 wt. %. The highest saturation magnetization of 5.38 emu/g was obtained for the electrospun yarn containing 1 wt. % Fe3O4, corroborating 13.6 times greater features than that of the fibrous membrane with a similar chemical composition. The obtained results implied that the as-spun fibrous yarn could be a great candidate as a surgical suture with the release capability of bioactive agents under a magnetic field.
