In this review, a comprehensive systematic study of the research background, developments, classification, trends, and advances over past few years in on new electromagnetic interference (EMI) shielding materials will be described. The following groups for EMI discussed: biochars, scaffolds, rare earth, ferrite-based materials. We selected two novel, organic, lightweight (biochars scaffolds) compared their effectiveness to inorganic (ferrite earth materials). This article broadly discuss performance, basic principles shielding, preparation methods materials, application prospects. Biochars are promising, eco-friendly, sustainable, renewable that can potentially used as filter polymer composites along with scaffolds. Scaffolds new-generation, easy-to-manufacture excellent performance. Rare (RE) plays an important role developing high-performance wave absorption due unique electronic shell configurations higher ionic radii RE elements. Ferrite-based often combined other components achieve enhanced mechanical strength, electrical thermal conductivity. Finally, current challenges future outlook highlighted hope obtaining guidelines development application.

Robust Single-Walled Carbon Nanotube-Coated Aramid Fibers with Tunable Conductivities for Broadband Radar Absorption in Honeycomb Structures

Single-walled carbon nanotubes (SWNTs), renowned for their high strength and electromagnetic properties, provide a potential solution next-generation honeycomb-structured radar-absorbing materials (HRAMs). However, the integration of SWNTs into HRAMs is hindered by challenges including poor dispersion, wash-off loss, absence scalable, compatible fabrication methods. Herein, we address these synthesizing tunable conductive SWNT-coated aramid fibers (SWNT-AF) via continuous dip-coating method integrating them paper-based composites (APBC) to fabricate HRAMs. The SWNT-AF serve as both structural reinforcements dielectric loss centers within APBC, avoiding direct dispersion pulp thereby mitigating agglomeration loss. optimized reinforced with tailored fibers, exhibit improved resulting in enhanced microwave absorption performance. fabricated achieve an effective bandwidth 14.8 GHz (2.0-18.0 GHz) ultralow SWNT loading 0.2 wt % thin thickness only 30 mm, demonstrating reflection -47.78 dB. These results highlight lightweight, broadband stealth applications.
