CoFe2O4/N-doped reduced graphene oxide aerogels for high-performance microwave absorption

Facile Synthesis of Ultralight and Porous Melamine-Formaldehyde (MF) Resin-Derived Magnetic Graphite-Like C3N4/Carbon Foam with Electromagnetic Wave Absorption Behavior

“…Among these three absorbers, MCMF shows the optimal impedance matching with minimum reflection of the incident EMW at the interface between the air and absorber. The Zin value of MCMF with a thickness of 3.90 mm is very close to 1, indicating that the obtained most excellent EMW absorption behavior among the same type of absorbers [44][45][46][47] is attributed to the optimal dielectric-magnetic coupling in MCMF composites [48].…”

Porous carbon materials for microwave absorption

“…[2][3][4] Therefore, developing advanced microwave absorption (MA) materials to eliminate unwanted EM energy has attracted great interest at the global scale. [5][6][7][8][9] Usually, ideal MA materials should be thin in thickness, light in weight, wide in bandwidth, and strong in absorption. Furthermore, to increase the service life of MA materials, they need to display excellent environmental corrosion resistance (such as high temperature and humidity resistance, and thermal oxidization stability).…”

“…[12][13][14][15][16][17][18][19][20] For example, there have been lots of studies on graphene and carbon nanotubes (CNTs) applied in MA fields due to their strong electrical conductivities, low percolation thresholds, and organized nanostructures. 6,11,14, However, the costeffective and large-scale production of graphene and CNTs remains a crucial challenge for commercial application, which seriously hinders their applications. Recently, porous carbon (PC) materials combined with carbon and porous features can be produced by a facile and simple synthesis method with low-cost raw materials, which has aroused renewed interest.…”

Modeling dielectric permittivity of polymer composites filled with transition metal dichalcogenide nanoparticles

“…14 In particular, the Wang group has recently demonstrated exceptionally high EM absorption of polymers reinforced with (i) superparamagnetic cobalt ferrite nanospheres decorated with reduced graphene oxide (rGO), 15 (ii) capsule-like structures of CoFe 2 O 4 nanoparticles enriched with rGO and covered with poly(vinylpyrrolidone), 16 (iii) binary composites of termochromic samarium-iron garnet Sm 3 Fe 5 O 12 with cobalt ferrite furnished with rGO, 17 (iv) CoFe 2 O 4 nanospheres embedded into MoS 2 nest-like nanostructures, 18 and (v) graphene oxide aerogels loaded with cobalt ferrite nanoparticles. 19…”
