Review of electromagnetic interference shielding materials fabricated by iron ingredients

Abstract

Iron with carbonaceous materials, conducting polymers, dielectric materials or insulating polymers is reviewed.

Biochar-iron composites as electromagnetic interference shielding material

“…The contribution of carbon material to EMI shielding effectiveness was reported Dang et al [16]. The carbon fiber intensified the shielding effectiveness of polyacrylamide/wood fiber composite from 0.41 to 41 dB in the X-band frequency range (8)(9)(10)(11)(12).…”

“…Moreover, composites of carbon and iron are investigated as effective materials for EMI protection. Especially, Fe-oxide-carbon composites have been reported to be effective in the absorption mechanism [10][11][12]. These composites also reduce the reflection.…”

Comparative study of polymer-based nanocomposites microwave absorption performance in X–band

“…The rapid development of electronic gadgets, commercial, biological, military and defence systems creates electromagnetic (EM) noise known as EM pollution. EM pollution causes human health diseases like sleeping disorders, nervousness and headache [1]. This pollution worsens the functioning of electronic equipment and their durability.…”

“…These shields also act as radiation barriers to other electronic components in the devices. In the second method, the shielding materials are made more effective by incorporating dielectric particles into them which allows for reduction of thickness of the shielding material [1][2][3][4]. In current study the second method has been chosen knowingly absorption dominated microwave shielding.…”

“…Conducting carbon based materials like carbon black (CB) [1,13,23], carbon nanotube (CNT) [1, 5-8, 13, 16, 20, 23], carbon nano fiber (CNF) [1,8,23] and graphene [1-4, 9, 11-15, 17-23] were exhibited EM shielding due to their remarkable electromagnetic properties. Among all, graphene posses electrical conductivity value of 6000 SCm −1 , high aspect ratio and good microwave attenuation.…”
