ABSTRACT The increasing proliferation of electronic devices and advanced communication networks has resulted in heightened electromagnetic interference (EMI), posing significant challenges both technological environmental contexts. Traditional EMI shielding materials, such as metals composite coatings, offer limited adaptability are unable to meet the dynamic demands modern systems. Recent advancements have introduced smart stimuli‐responsive materials for shielding, which provide real‐time tunability, thereby addressing limitations conventional static solutions. These leverage various mechanisms—such compressive tensile strains, phase transitions, shape memory effects, responses chemical agents, humidity, or crossover angle changes—to dynamically adjust their effectiveness (EMI‐SE). This review provides an in‐depth analysis recent progress technologies, highlighting tunable mechanisms, material compositions, applications. Furthermore, it discusses existing potential future research directions required advancement this technology. By enabling environments, present a promising solution telecommunications, wearable electronics, aerospace, defense sectors.

ABSTRACT To regulate the mechanical and thermal properties of epoxy resin (Ep) achieve controllability its shape memory response, this work involves physical modification Ep using polyethylene glycol (PEG), leading to development Ep/PEG (EpP) films. As PEG content increases, EpP gradually transitions from rigid flexible. Notably, breaking strain EpP‐30 with 30% increased by 27.19% compared EpP‐0 without PEG. The are also modulated content, glass transition temperature (T g ) decreasing as increases. Specifically, T is reduced 33.44°C EpP‐0. developed exhibits excellent performance, response can be adjusted through content. Furthermore, demonstrates dual triple‐shape functions. In summary, achieves regulation PEG, successfully developing a controllable temperatures capabilities for triple responses.

Abstract Multi‐stimuli responsive shape memory composites (MS‐SMPCs) have broad potential in fields such as adaptive architecture and aerospace applications but face limitations response speed, mechanical performance, reliability. To address this, this study designs a two‐dimensional woven SMPC based on continuous carbon fiber (CCF)/Fe 3 O 4 nanoparticles/shape polyurethane (SMPU) composite filaments investigates its properties under thermal, electrical, magnetic stimuli. The results demonstrate that the exhibits excellent effects all three uniform distribution of particles enhances SMPC's recovery performance. As content increases from 3% to 9%, time decreases 37.5 9 s. CCF improves strength, electrical conductivity, performance volume fraction 12.7% 29.5%, modulus single‐layer sample by seven times. highest efficiency (SRE) is 0.63 stimulation, followed 0.57 stimulation 0.37 thermal stimulation. adaptability maintain efficient various environments has significant practical value, particularly smart textiles flexible robotics. Highlights Woven with thermal–electrical–magnetic stimuli prepared. Magnetic are uniformly distributed SMPC. improve strength behavior
