Fabrication (ferrofluid/polyvinyl alcohol) magnetic nanofibers via co-axial electrospinning

Magnetic nanofibers were fabricated using polyvinyl alcohol as a shelter for magnetic nanoparticles suspension. The transformation process from ferrofluid and polyvinyl alcohol solution to magnetic nanofibers has been investigated where the response variable analyzed was morphology. The results obtained from the high resolution transmission electron microscopy observation revealed that the flow rate and voltage have significant effect on desirable morphology. Nanofibers with fancy morphology and better aligned order tend to have higher elasticity contributed by the better alignment of lamellae along the fibers axis and molecular orientation. The fabricated nanofibers were ultra-fine with nanosize diameter within the range of approximately 290-380 nm
