Due to the increasing use of gigahertz electromagnetic waves in industrial, commercial and military application the electromagnetic interference as a specific kind environmentalpollution is drawing more attention recently. In order to protect people from the harm of electromagnetic wave, thedemands to develop microwave absorbents with high absorption rate, thin coating, and wide absorption band, light weight, thermostable, anti-abrasion and low cost are everincreasing [1–3]. In this study, Polyacrylonitrile (PAN) fibers involving ZnO/Fe3O4 /IL additives were prepared as an electromagnetic interference shielding material by electrospinning
