Exfoliated graphite nanoplatelet (xGnP) filled EVA/EOC blends nanocomposites for efficient microwave absorption in the S-band (2–4 GHz)

Recent advancements in the electromagnetic interference shielding performance of nanostructured materials and their nanocomposites: a review

“…4 Accordingly, the EMI shielding properties of nanocarbon incorporated in polymethylmethacrylate (PMMA), polystyrene (PS), epoxy resin (ER), polypropylene (PP), polyurethane (PU), polyvinylalcohol (PVA), polydimethylsiloxane (PDMS), polyimide (PI), polyethylene (PE), natural rubber (NR) and few other polymers are reviewed below. 66–213…”

“…Recently, polymer nanocomposites of graphene have demonstrated the most cutting-edge performance in electromagnetic wave absorbing and shielding fields. 134–213…”

“…210 The exfoliated graphite nanoplatelets filled ethylene vinyl acetate (EVA)/ethylene-octene copolymer (EOC) blend composite prepared by melt mixing attained EMI SE values of −67.63 in the frequency range of 2–4 GHz. 211 Maya et al 212 prepared the RGO/MWCNT (4 phr) hybrid filler reinforced polychloroprene rubber (CR) composites using a two-roll mill mixing technique and attained the EMI SE of 11.87 dB @ 3.5 GHz due to the synergistic effect. PVA/SRGO (selectively reduced graphene oxide) film showed considerable improvement in conductivity at a low percolation threshold (0.5 phr) due to the formation of a conducting network between PVA and SRGO as shown in Fig.…”

Ultralow percolation threshold biodegradable PLA/PBS/MWCNTs with segregated conductive networks for high‐performance electromagnetic interference shielding applications

“…Constructing segregated structures in CPCs through melt blending can effectively reduce the percolation threshold of CPCs. 17,18 Conductive fillers in normal samples are randomly distributed in the polymer matrix, while for the samples with segregated structures, they are selectively dispersed in a particular polymer or on the interface of the two-phase polymers, thus forming a complete conductive network with a lower addition of fillers. 19,20 Since nondegradable petroleum-based polymers are the most used polymer matrices for CPCs, their widespread use has triggered environmental crises such as depletion of petroleum resources and environmental contamination.…”

Reduced Graphene Oxide/Fe3O4/Polyaniline Ternary Composites as a Superior Microwave Absorber in the Shielding of Electromagnetic Pollution

“…The interference of electromagnetic wave (EM) is an undesirable manifestation of radiation originating from different electronic instruments/appliances at different frequencies. − As a result, their performance is effected in terms of speed and secrecy resulting in the loss of data storage, revenue, efforts, and time. , In addition, it also effects human health leading to leukemia, miscarriages, brain cancer, and, in some cases, even death. , Therefore, a considerable amount of research has been focused on developing suitable electromagnetic interference (EMI) shielding materials for suppression of such electromagnetic pollution either by reflection, absorption, or multiple reflections.…”
