Fabrication and characterization of magnetic nanocomposites by electric fields assisted electrospinning

摘要

A magnetic and electric fields assisted electrospinning, in which a charged copper ring was placed between the needle and the two paralleled magnets receivers, was presented to produce aligned polyacrylonitrile/graphene/Fe3O4 (PAN/Gr/Fe3O4) magnetic composite nanofibers. Characterizations of the magnetic composite nanofibers were investigated by means of scanning electron microscopy, Fourier transform infrared spectroscopy, high-resistance meter, and other methods. The results showed that Gr and Fe3O4 nanoparticles are suitable additives to improve alignment degree and conductive properties of nanofibers.
