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.
随着自动化行业的发展，电磁干扰（EMI）一直呈上升趋势，给终端用户带来极大困扰，并影响电子设备。这个问题并不新鲜，已经开展了大量工作，但遗憾的是，该问题尚未得到彻底解决。因此，本综述旨在评估先前在X波段及以上频率范围内对石墨烯@铁、石墨烯@聚合物、铁@聚合物和石墨烯@铁@聚合物复合材料相结合的电磁屏蔽材料进行的研究，以应对电磁干扰。还使用VOSviewer进行关键词分析，以展示这些研究之间的相互联系。基于所开展的综述发现，应对电磁干扰最理想的材料是聚合物基复合材料，其表现出显著效果。这是因为聚合物具有柔韧性，能与其他材料形成更好的结合。聚二甲基硅氧烷（PDMS）、聚苯胺（PANI）、聚甲基丙烯酸甲酯（PMMA）和聚偏氟乙烯（PVDF）在X波段频率范围内有效，而PDMS、环氧树脂、PVDF和PANI在X波段频率范围以上具有良好的屏蔽效果。然而，仍有许多新的组合需要研究，因为大多数屏蔽效果是在X波段频率范围内实现的，而在更高频率范围内还需要开展大量工作。
