“…As the applications of electronic science and technology advance, the unavoidable electromagnetic interference (EMI) problem has attracted considerable attention due to the negative effect of excessive electromagnetic (EM) waves on equipment and human health. [1][2][3][4][5][6][7][8][9][10] EMI shielding is the most effective way to eliminate EMI. Consequently, researchers have devoted considerable effort to the development of high-performance EMI-shielding materials.…”

“…The rapid development of communication technology and electronic devices has inevitably led to an increase in the electromagnetic energy density in the natural environment. − This not only causes electromagnetic interference (EMI) that disrupts the functioning of electronic devices but also poses a potential risk to human health. − To eliminate the hazards of electromagnetic radiation, the use of electromagnetic shielding materials that can block radiation propagation is an effective approach. , With the rise in the use of flexible optoelectronic devices, it is essential to develop flexible, transparent, and highly efficient electromagnetic shielding materials. , Researchers have investigated several materials, such as graphene, − conductive polymers, micro-metal mesh, and metal nanowires (NWs), for developing flexible, transparent electromagnetic shielding films. Among these, metal-nanowire-based flexible transparent electromagnetic shielding films have gained significant attention due to their low cost and ease of fabrication.…”

Although metal nanowires (NWs), such as silver NWs, are ideal materials for flexible transparent electromagnetic shielding films, the challenge of obtaining absorptive shielding films with high transmittance and shielding efficiency (SE) still exists. To address this issue, this study used iron nanowires (Fe NWs) with excellent microwave absorbing properties to construct structures with ordered NW distributions. A series of polyethylene terephthalate (PET)/Fe NWs/poly (3,4-ethylenedioxythiophene) (PEDOT) electromagnetic interference (EMI) shielding films were prepared using the magneticfield-induced orientation. The results demonstrate that the ordered Fe NW network structure can effectively overcome the problem of the trade-off between light transmittance and EMI SE. Specifically, at a Fe NW surface density of 201.78 mg/m 2 , the ordered PET/Fe NWs/ PEDOT films demonstrated a 49.06% increase in light transmittance and a 32.94% increase in EMI SE (19.37 dB), compared to the films with randomly distributed Fe NWs. Furthermore, constructing a double-layer Fe NW network with a stagger angle of 45°at the same surface density increased the EMI SE by 73.2% relative to the monolayer-ordered Fe NW structure, reaching an SE value of 33.54 dB, while maintaining almost unchanged light transmittance. Additionally, the PET/Fe NWs/PEDOT films maintain 97.4% of EMI performance after 3000 bending cycles. Overall, this study provides a new approach for creating high-performance flexible transparent EMI shielding films.

The emergence of metamaterials and their continued prosperity have built a powerful working platform for accurately manipulating the behavior of electromagnetic waves, providing sufficient possibility for the realization of metamaterial absorbers with outstanding performance. However, metamaterial absorbers composed of metallic materials typically possess many unfavorable factors, such as non‐adjustable absorption, easy oxidation, low‐melting, and expensive preparation costs. The selection of dielectric materials provides excellent alternatives due to their remarkable properties, thus dielectric‐based metamaterial absorbers (DBMAs) have attracted much attention. To promote breakthroughs in DBMAs and guide their future development, this work systematically and deeply reviews the recent research progress of DBMAs from four different but progressive aspects, including physical principles; classifications, material selections and tunable properties; preparation technologies; and functional applications. Five different types of theories and related physical mechanisms, such as Mie resonance, guided‐mode resonance, and Anapole resonance, are briefly outlined to explain DBMAs having near‐perfect absorption performance. Mainstream material selections, structure designs, and different types of tunable DBMAs are highlighted. Several widely utilized preparation methods for customizing DBMAs are given. Various practical applications of DBMAs in sensing, stealth technology, solar energy absorption, and electromagnetic interference suppression are reviewed. Finally, some key challenges and feasible solutions for DBMAs’ future development are provided.
