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

Synthesis and characterization of hybrid conducting composites based on polyaniline/magnetite fillers with improved microwave absorption properties

“…Over the last decade, many researches focused on a new type of hybrid material based on polymers-matrix composites containing dielectric or/and magnetic fillers [18]. Combination of PANI with other organic or inorganic materials provides new materials with tailored properties, suitable for various electrical and electromagnetic applications in aeronautic or aerospace areas and to avoid electromagnetic pollution arising from various electronic devices operating in microwave frequency range [19,20]. The dispersion of polyaniline and magnetite fillers in an insulating polymer matrix (thermoplastic or thermosetting) produces different composites that can absorb and reflect electromagnetic radiation by changing its conductivity, its dielectric constant and its magnetic permeability.…”

Synthesis, dielectric and magnetic characteristics of poly(1-vinyl-1,2,4-triazole) (PVTri)–barium hexaferrite composite

“…Coating inorganic particles 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 [1][2][3].…”

Preparation and microwave absorption property of graphene/BaFe12O19/CoFe2O4 nanocomposite

“…It is believed that proper permittivity and permeability are advantageous to enhance the microwave absorbing properties. In addition, the presence of graphene reduces the magnetic-coupling effect between grains, while increases effective surface anisotropy of the grains [29]. Above these reasons make the as-prepared graphene/BaFe 12 nanocomposite at different specimen thicknesses is shown in Fig.…”
