Abstract
With advancements in the automated industry, electromagnetic inferences (EMI) have been increasing over time, causing major distress among the end-users and affecting electronic appliances. The issue is not new and major work has been done, but unfortunately, the issue has not been fully eliminated. Therefore, this review intends to evaluate the previous carried-out studies on electromagnetic shielding materials with the combination of Graphene@Iron, Graphene@Polymer, Iron@Polymer and Graphene@Iron@Polymer composites in X-band frequency range and above to deal with EMI. VOSviewer was also used to perform the keyword analysis which shows how the studies are interconnected. Based on the carried-out review it was observed that the most preferable materials to deal with EMI are polymer-based composites which showed remarkable results. It is because the polymers are flexible and provide better bonding with other materials. Polydimethylsiloxane (PDMS), polyaniline (PANI), polymethyl methacrylate (PMMA) and polyvinylidene fluoride (PVDF) are effective in the X-band frequency range, and PDMS, epoxy, PVDF and PANI provide good shielding effectiveness above the X-band frequency range. However, still, many new combinations need to be examined as mostly the shielding effectiveness was achieved within the X-band frequency range where much work is required in the higher frequency range.
Highlights
Electromagnetic interference (EMI) has emerged as a global issue due to the rapid growth of electronic devices and their usage in day-to-day life [1]
As the purpose of this study is to review the past literature of electromagnetic inferences (EMI) shielding materials, only those articles which were available with the combination of Graphene@Iron, Graphene@Polymer, Iron@Polymer and Graphene@Iron@Polymer composites were considered
The results showed the high EMI shielding effectiveness of Fe3 O4 @graphene nanoplates (GNPs) compared to other samples having equivalent loading of GNP and Fe3 O4
Summary
Electromagnetic interference (EMI) has emerged as a global issue due to the rapid growth of electronic devices and their usage in day-to-day life [1]. Owing to the increased usage of these electromagnetic devices, radiation of the electromagnetic (EM) wave has become a serious concern because these radiations become disastrous for electronic equipment and affecting human health [5]. With the advancement in technologies, human exposure to electromagnetic fields is getting common and unavoidable [6,7,8]. Electromagnetic waves do not deflect by any magnetic or electric field and cause serious issues [9]. Electromagnetic waves are causing damages in various forms such as changes in physiological indices, genetic effects, health, and immune functions
