Integration of MCMBs/MWCNTs with Fe₃O₄in a flexible and light weight composite paper for promising EMI shielding applications

Abstract

A hybrid three phase system containing MCMBs/MWCNTs/Fe3O4 in the form of a highly flexible and light weight composite paper is fabricated by simple cost effective strategies and is promising EMI shielding applications.

Oxidized multiwall carbon nanotube/silicone foam composites with effective electromagnetic interference shielding and high gamma radiation stability

“…If the distance between the reecting surfaces or interfaces is considerably larger than the skin depth, the contribution from multiple reections is merged in the absorption. 20 Therefore, the SE T has the following expression: At the same content of o-MWCNT, the SE T of the composites is almost independent of frequency in the measured bands, which is consistent with other types of polymer composites such as MWNTs/PS/PMMA, 21 MWCNT/PU 22 and PS/MWCNT/Graphite Nanoplate Nanocomposites. 23 As shown in Fig.…”

Lightweight carbon-red mud hybrid foam toward fire-resistant and efficient shield against electromagnetic interference

“…The increase in complex permittivity with an increase in red mud content within the carbon foam can be ascribed to enhanced dipole orientation polarization and interfacial polarization, considering the other mechanisms such as electronic and ionic polarization. It is known that the red mud has multiphase elements (metal oxides) which create interfacial polarizations between metal oxides and carbon atoms 41 . Additionally, these metal oxides create defects in carbon structure and work as a polarizing center, resulting in high permittivity in carbon-mud hybrid foams.…”

“…Additionally, these metal oxides create defects in carbon structure and work as a polarizing center, resulting in high permittivity in carbon-mud hybrid foams. For better understanding, the value of ε′ and ε″ can be described by Debye theory 41 .…”
