Superparamagnetic ZnFe₂O₄ Nanoparticles-Reduced Graphene Oxide-Polyurethane Resin Based Nanocomposites for Electromagnetic Interference Shielding Application.

ABSTRACT: Superparamagnetic ZnFe₂O₄ spinel ferrite nanoparticles were prepared by the sonochemical synthesis method at different ultra-sonication times of 25 min (ZS25), 50 min (ZS50), and 100 min (ZS100). The structural properties of ZnFe₂O₄ spinel ferrite nanoparticles were controlled via sonochemical synthesis time. The average crystallite size increases from 3.0 nm to 4.0 nm with a rise of sonication time from 25 min to 100 min. The change of physical properties of ZnFe₂O₄ nanoparticles with the increase of sonication time was observed. The prepared ZnFe₂O₄ nanoparticles show superparamagnetic behavior. The prepared ZnFe₂O₄ nanoparticles (ZS25, ZS50, and ZS100) and reduced graphene oxide
