Abstract

Electromagnetic Fe3O4@polyaniline (PANI) nanofibers with high aspect ratio were realized by combining magnetic-field-induced (MFI) self-assembly and in situ surface polymerization of aniline. The key to fabrication is to induce chaining of the amino-Fe3O4 microspheres during the PANI coating process, which allows additional deposited PANI to warp entire chains into nanofibers. Hydrogen bonds are thought to be the driving force that makes aniline form a PANI coating shell instead of irregular sheets. Compared to the Fe3O4@PANI microspheres, higher magnetization saturation value and conductivity value were achieved in the Fe3O4@PANI nanofibers, which hold high promise for potential applications in microwave absorbents, electromagnetic shielding coatings, and other usage associated with conventional electromagnetic techniques.
