Abstract The revolution of millimeter‐wave (mmWave) technologies is prompting a need for absorption‐dominant EMI shielding materials. While conventional materials struggle in the mmWave spectrum due to their reflective nature, this study introduces novel film with ultralow reflection (<0.05 dB or 1.5%), ultrahigh absorption (>70 98.5%), and superior 99.99999%) across triple frequency bands thickness 400 µm. By integrating magnetic composite layer (MCL), conductive patterned grid (CPG), double‐walled carbon nanotube (DWCNTF), specific resonant frequencies electromagnetic waves are transmitted into minimized reflection, trapped dissipated between CPG DWCNTF. design factors frequencies, such as geometry MCL refractive index, systematically investigated based on wave propagation theories. This innovative approach presents promising solution effective materials, implications mobile communication, radar systems, wireless gigabit communication.

With the continuous development of small and medium-sized electronic devices, which bring convenience to people’s lives, electromagnetic wave (EMW) pollution has emerged as a significant issue. The materials with interference (EMI) shielding capabilities for protection against harmful radiation plays vital role. Currently, wide range multifunctional, lightweight EMI have been created address various environmental requirements. However, single material difficult meet requirements high-speed transmission equipment because when such devices operate at high speeds, they typically generate elevated temperatures, excessive further exacerbates heat accumulation, reducing both efficiency lifespan. Therefore, thermal management is essential lower operating temperatures ensure optimal performance. Phase change (PCMs) are known storing large amount energy, potential in management, so flexible phase composites (PCCs) emerged. This review provides detailed examination based on fillers, PCMs latest advancements developing new PCCs. Finally, we suggest some research directions PCCs, hoping contribute rapid advancement next-generation electronics, human artificial intelligence.

Abstract The desire to reduce secondary pollution from shielded electronics devices demands electromagnetic interference (EMI) shields with high green index (GI), which is the ratio of absorbance over reflectance. Achieving GI values simultaneously shielding effectiveness (SE) 50 dB a serious unresolved challenge. Reducing impedance mismatch between shield and free space key reducing reflection incoming radiation enabling more penetration into body for absorption. Here sandwich structure gradient conductivity introduced that achieves combination (≈2) SE (70 dB). top layer deliberately uses an aerogel low MXene nanoribbon in PEDOT:PSS polymer boost GI. also reduces permittivity shield, as another way nonmagnetic material. bottom consists nanosheet–polymer its metal‐like provide SE. This successful demonstration expected lead other novel ways create EMI shields.
