Abstract: Composite nanofibers were fabricated by coaxial electrospinning, using chitosan/poly(vinyl pyrrolidone) (CS /PVP) as sheath and Fe3O4/PVP as core. The morphology, chemical composition and magnetic characteristics of composite nanofibers were characterized by means of scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). Experimental results indicated that the composite nanofibers had a uniform structure and smooth surface, diameter between 350-800 nm, well surface morphology, and crystalline Fe3O4 distributed in nanofibers. Composite nanofibers showed a certain magnetic property, and could be an excellent composite material for the application of biomedicine.
