Synthesis of conducting ferromagnetic nanocomposite with improved microwave absorption properties

Electrical Conductivity, Dielectric Behavior and EMI Shielding Effectiveness of Polyaniline-Yttrium Oxide Composites

“…24 Such conducting polymer based composites are expected to exhibit EMI shielding and electrostatic dissipation of charges (ESD) due to their modified electrical and dielectric properties. 25 Most of the conducting polymer composite systems studied in the literature refer to their physical characteristics and mechanism of electric transport, [4][5][6][7][8][9][10][11][12][13][14][15][16]19,20,22 but the studies on EMI shielding properties in the low frequency range are very limited.…”

Synthesis of ferrofluid based nanoarchitectured polypyrrole composites and its application for electromagnetic shielding

“…Therefore, conjugated polymers combined with magnetic nanoparticles to form ferromagnetic nanocomposites provide an exciting system to investigate the possibility of exhibiting novel functionality to provide the better microwave absorption properties [19e21]. Recently, Dhawan et al have investigated by the microwave absorption properties of the g-Fe 2 O 3 incorporated polyaniline, PEDOT nanocomposites with different loading [22,23]. The properties of these polymer composites depend on their micro/nanostructures and morphologies which is controlled by the synthesis method.…”

Facile synthesis, magnetic and microwave absorption properties of Fe3O4/polypyrrole core/shell nanocomposite

“…Inorganic nanoparticles coated with conducting polymer to form core/shell structured materials has been demonstrated to be an effective strategy to enhance the stability of composites and widen the applications because of the strong electronic interaction between the inorganic core and polymer shell [4,5]. Polypyrrole (PPy), as a typical conducting polymer, has drawn more attention due to its relatively easy preparation, excellent environmental stability and good electrical conductivity [6,7].…”
