Optimization of CoFe2O4 nanoparticles and graphite fillers to endow thermoplastic polyurethane nanocomposites with superior electromagnetic interference shielding performance

“…Further, these accumulations of charge carriers at the interfaces of CoFe 2 O 4 nanoparticles and graphite result in an increase in the interfacial area. 63 The increase in the interfacial area will suggest an enhancement in the energy storage capacity and further absorption characteristics of the polymer nanocomposites. 6,64 Further, Fig.…”

Effect of electron irradiation on alternating current electrical properties of gelatin – cadmium sulfide nano‐composite films

“…Furthermore, the primary shielding mechanism, reflection, necessitates a sufficient electrical conductivity, whereas the second, absorption, necessitates the presence of magnetic or electric dipoles [41]. Various filler materials used to make nanocomposites with a wide range of electrical conductivity and/or electromagnetic properties such as permittivity or permeability have been explored earlier [42][43][44][45][46][47]. Improvements in dielectric properties will also help nanocomposites films improve their electromagnetic interference shielding properties [48].…”

MWCNT-Reinforced Polymethacrylimide Foams for Broadband Electromagnetic Wave Absorption

“…The proliferation and advancement of electronic devices have led to increased levels of electromagnetic radiation, which can interfere with and potentially damage electronic equipment while posing health risks to humans. − Addressing the secondary pollution caused by electromagnetic reflection, there has been a surge in interest in electromagnetic wave absorbing materials. These materials convert electromagnetic wave energy into alternative forms, presenting the most efficacious strategy for mitigating electromagnetic pollution. − Ideal absorption materials for practical applications should possess robust absorption capabilities, an extensive effective absorption bandwidth, low weight, and minimal load. − A variety of materials with strong electromagnetic wave attenuation properties have been developed, including ferrites, metals, carbon-based materials, ceramics, conductive polymers, and composites. − However, their limited effective absorption bandwidth (EAB < 10 GHz) restricts their widespread application across different frequency bands. − …”
