UV-modification of Ag nanoparticles on α-MoCx for interface polarization engineering in electromagnetic wave absorption

“…Researchers have recently developed various electromagnetic wave absorbing materials (EWAMs) to weaken EM radiation or convert electromagnetic energy into heat energy. 7,8 Electromagnetic wave materials have a wide range of applications in EMI (electromagnetic interference) shielding [9][10][11] and civilian-military stealth coatings [12][13][14][15] and have thus attracted significant attention. As representative EWAMs, carbon-based composite materials, [16][17][18][19][20][21][22][23][24][25][26][27] transition metallic composites, [28][29][30][31][32][33][34][35] and non-metallic ceramic compounds [36][37][38][39][40] have shown high electromagnetic wave absorption and wide band coverage performances.…”

Magnetic Resonance Modulation in Ferrocene-alkyne Conjugated Polymer for Electromagnetic Wave Absorption

“…With the development of technology electromagnetic waves have been used in all aspects of life, such as microwave ovens, cell phones, and so on. − But electromagnetic waves bring us convenience and at the same time will produce radiation to harm people’s central nervous system, cardiovascular system, and so on. − Therefore, many electromagnetic wave absorbing materials have been developed to reduce the harm of electromagnetic waves, mainly including carbon-based materials (graphene, carbon fiber, carbon nanotubes), − magnetic materials (magnetic metals, oxides, alloys), − magnetic carbon composites, − and other nanomaterials (carbide, nitride, sulfide, MXene). − It is well-known that electromagnetic wave-absorbing materials dissipate electromagnetic waves mainly through dielectric and magnetic losses . Among these reported wave-absorbing materials, almost all of them are based on dielectric loss or electromagnetic loss coupling to regulate the electromagnetic wave-absorbing performance, which leads to the difficulty of revealing the specific influence mechanism of individual magnetic factors on the wave-absorbing performance.…”
