In this work, polyacrylonitrile (PAN) was electrospun with and without magnetic nanoparticles (aluminum-doped iron oxide) and was turned into magnetic nanofibers. The results showed that nanofibers diameter decreased from 700 nm to 300 nm by adding nanoparticles. Furthermore, pure PAN nanofibers were indicated to have a low magnetic ability due to polar bonds that exist in their acrylonitrile groups. Obviously, by adding only 4 wt% of the nanoparticles to PAN nanofibers, magnetic ability soared by more than 10 times, but at a higher percentage, it was shown to change just a little due to negative interaction among nanoparticles. This event relates to antiferromagnetically coupling of nanoparticles due to incomplete dispersion at a higher percentage.
