Infrared and microwave absorbing properties of BaTiO3/polyaniline and BaFe12O19/polyaniline composites

A new microwave absorber based on antimony-doped tin oxide and ferrite composite with excellent electromagnetic match

“…However, single conventional ferrite is hardly to satisfy the appropriate electromagnetic match which is essential for strong absorption behavior in wide frequency range. In recent years, a number of investigations have been well documented on the composite microwave absorbing materials based on ferrite [8][9][10][11]. For examples, carbon nanotube is compounded with ferrite due to its high complex permittivity [12], and polyaniline is compounded with ferrite because of its controllable resistivity [13].…”

Synergetic improvement in electromagnetic interference shielding characteristics of polyaniline-coated graphite oxide/γ-Fe2O3/BaTiO3 nanocomposites

“…GO and the ferroelectric BaTiO 3 improved EMI SE of nanocomposite by decreasing the electrical interference effectively due to the electrical properties of BaTiO 3 [27,52]. On the other hand, the ferromagnetic g-Fe 2 O 3 improved EMI SE of nanocomposite by decreasing the magnetic interference [31].…”

Thermal infrared and microwave absorbing properties of SrTiO3/SrFe12O19/polyaniline nanocomposites

“…Particularly they are important in determining their high frequency characteristics. So, infrared and microwave absorbing properties of BaTiO 3 /polyaniline and BaFe 12 O 19 /polyaniline composites were investigated by Wu, too [15]. Recently, nonconducting infrared-absorbing thin films were prepared by black silicon and bismuth by Li and Gradhand [16,17].…”
