Abstract

Abstract: In this work, a novel and facile technique, epoxy-water-inorganic filler suspended emulsion polymerization, was proposed to fabricate 3D network porous graphene nanoplatelet (GNP)/Fe3 O4 /epoxy nanocomposites with low density of 0.34–0.73 g/cm 3 . The obtained porous nanocomposite with 7 wt% graphene nanoplatelets and 7 wt% Fe3 O4 nanoparticles loading exhibited satisfactory specific electromagnetic interference (EMI) shieling effectiveness of ∼37.03 dB/(g/cm 3 ), which was much higher than that of the solid counterparts (28.30 dB/(g/cm 3 )). In addition, the porous GNP/Fe3 O4 /epoxy nanocomposites also possessed outstanding thermal stability and mechanical property, which makes it a potential EMI shielding material in the fields of aerospace and electronic industries.
