Enhanced microwave absorption properties of the milled flake-shaped FeSiAl/graphite composites

Comparison of the Magnetic and Absorption Properties of Flaky Super Sendust and Sendust Alloys

“…Much work has been conducted on Fe-Si-Al to improve its magnetic properties; this includes surface modification, 9,10 mixing the magnetic material with carbonaceous 11,12 or dielectric materials, 13 and atom substitution. 14 However, the brittleness of the Fe-Si-Al alloy limits its effective application for microwave absorption.…”

Electronic structure and soft magnetic properties of Se/FeSiAl (110) films

“…Sun et al [13] studied the irregular-shaped FeSiAl powder mixed with graphite. The results demonstrated that the milled FeSiAl/graphite absorbers possess higher permittivity, slightly increased permeability, and better microwave absorption properties than those of raw FeSiAl powders in the frequency range of 2-18 GHz.…”

Evolution of double magnetic resonance behavior and electromagnetic properties of flake carbonyl iron and multi-walled carbon nanotubes filled epoxy-silicone

“…Electromagnetic (EM) waves absorbing materials in the frequency range of [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] GHz are important for both commercial and military applications, for example, protect the electronic devices and components, reduce the RCS for stealth systems [1,2]. It is also well known that the absorption of EM waves was worked by dissipating the EM energy into heat via magnetic and/or dielectric losses.…”

“…Commonly, the effectiveness of the EM wave absorbers were mainly depended on the EM properties of the absorber (such as the complex permittivity and permeability). Therefore, the control of the EM properties of absorbers is the key point for design the EM wave absorbers, and which can be satisfied by incorporating different dielectric and/or magnetic loss fillers into an insulating binder or matrix [3][4][5].…”

“…For the both conductive MWCNTs and magnetic particles filled composites, the EM 3 properties of such composites were depended on the fillers (MWCNTs and/or magnetic particles) content as well as the boundary conditions of the MWCNTs/magnetic particles/polymer interfaces. The reflection loss (RL) results also showed that such composites with both dielectric loss (owning to MWCNTs) and magnetic loss (owning to magnetic particles) were suitable to fabricated EM waves absorbing materials.…”
