Superior EMI shielding effectiveness of light weight and stretchable X-type hexaferrite-poly(vinylidene fluoride) laminated nanocomposite materials

In the present report, X-type hexaferrite-poly(vinylidene fluoride) laminated nanocomposite films have been fabricated by the solution casting method. The coexistence of a large magnetic moment of these X-type hexaferrite nanoparticles and a large electric dipole moment of polar PVDF matrix in the nanocomposite state make them more suitable for a wide range of EMI shielding applications. The high EMI shielding effectiveness of -69.5 dB at 9.9 and 11.7 GHz and -84.8 dB at 12.5 GHz and -83.8 dB at 14.1 GHz by the nanocomposite films have been observed. The high attenuation (>99.999999%) and wide bandwidth offers a completely unique nanocomposite material for the fabrication of affluent Radar Absorbing Materials (RAMs) to perform against the pollution caused by the high frequency EM radiations. Herein, the article also proposes the fabrication of electromagnetic shielding jacket and its application in daily life to combat against EM pollution.
