“…But it showed 28.3 dB SE at 10 GHz, with high shielding properties. In addition, Das et al prepared ZnO-XNBR (carboxylated nitrile-butadiene rubber)/rGO NFMs to enhance the functionality of their composites. The measured results showed that the SE of the composites could reach 34.2 dB, while also possessing good thermal management and self-healing capabilities.…”

With the rapid development of electronic information technology, the impact of electromagnetic waves (EMWs) on human health, information security, and precision electronic equipment cannot be ignored. Therefore, how to prepare lightweight, flexible and multifunctional materials to shield EMWs is an urgent problem to be solved. Electrospun nanofiber membranes (NFMs) have many merits, such as being lightweight and porous and having a high specific surface area, for electromagnetic interference (EMI) shielding. In this review, the mechanism of EMI shielding as well as the principle and development of electrospinning are first introduced. Then, the commonly used materials in electrospun NFMs for EMI shielding are summarized, and the factors affecting their EMI shielding performance are discussed. Afterward, the modification methods to enhance the EMI shielding performance of NFMs are investigated. Finally, the enhancement effects of different structures of NFMs on their EMI shielding performance are analyzed. This review can provide a more comprehensive understanding of electrospun NFMs used for EMI shielding and play a guiding role in preparing electrospun NFMs with excellent EMI shielding performance in the future.

“…RFGO displayed low oxygen content and high electrical conductivity, and the microwave-to-heat conversion effect, along with the DA bond, endowed its composite material with excellent EMI self-healing ability. Das et al 114 introduced reduced graphene oxide (RGO) nanosheets into an elastomeric matrix to prepare a zinc oxide cross-linked nitrile rubber (XNBR)/RGO elastomeric nanocomposite material, referred to as XZRG. The XZRG with 15 parts of RGO exhibited an EMI SE of 34.2 dB at a thickness of 1 mm and demonstrated a self-healing efficiency of 80% (Table 2).…”
