Abstract

A new structure of CoFe2O4 nanofibers/PVP flexible magnetic nanofibers has been successfully fabricated via electrospinning technology. Electrospun CoFe2O4 magnetic nanofibers are respectively incorporated into polyvinyl pyrrolidone (PVP) matrix and electrospun into flexible magnetic nanofibers named as CoFe2O4 nanofibers/PVP flexible nanofibers. The saturation magnetizations of obtained the flexible nanofibers can be tuned by adding various amounts of CoFe2O4 magnetic nanofibers. According to this way, we got stable magnetic fluid, which has been electrospun into magnetic nanofiber directly. The CoFe2O4 nanofibers encapsulated in the PVP nanofibers respond to an external magnetic field which is expected to be used in biomedical field. The design conception and construction technology are of universal significance to fabricate other flexible nanofibers..
