Abstract:
Electrospinning technology is a novel method of preparing nanofibers, which have the advantages of high aspect ratio, large specific surface areas and uniform diameter distribution. In general, ce-ramic spinel ferrites are prepared by the electrospinning of precursors in the presence of polymers followed by calcination. The calcination conditions will influence the crystal structure, morphology and magnetic properties of spinel ferrite nanofibers, such as calcination temperature and heating rate. The effects of ion substitution on magnetic properties of spinel nanofibers are due to the change of cation distribution on A and B sites. This paper summed up several important influence factors and ion substitution in the preparation of spinel ferrite nanofibers by electrospinning, which provide a feasible experimental method for the application of spinel ferrite nanofiers.
