Abstract The rapid development of global urbanization has exacerbated the urban heat island effect and electromagnetic radiation pollution. However, existing fabrics fail to provide both effective personal thermal management interference (EMI) shielding. To address this challenge, an asymmetric gradient porous fabric (AGPF) is developed using a delayed evaporation‐induced phase separation strategy. AGPF consists polystyrene‐block‐poly(ethylene‐ran‐butylene)‐block‐polystyrene (SEBS) transversely oriented liquid metal (LM) networks with wrinkled structures at bottom. Due complete sedimentation metal, SEBS maintains excellent solar reflectivity 93.9% atmospheric window infrared emissivity 94.7%. Upon activation by pre‐stretching, LM imparts high electrical conductivity enhanced stretchability AGPF, resulting in EMI shielding effectiveness 80.6 dB heating performance. Outdoor cooling tests further confirmed that achieves sub‐ambient ≈9.5 °C. Moreover, exhibits dynamically tunable performance across strain range 0% 200%, adapting complex outdoor environments. design provides advanced solution protect individuals from dual threats posed effects

A radiative cooling nanofabric was designed to reflect incoming solar light, exhibit strong emissivity, and simultaneously provide moisture-wicking properties, making it suitable for personal thermal management in hot outdoor environments. We developed a with fibrous sphere architecture, consisting of polyacrylonitrile-SiO2 poly(vinylidene fluoride-co-hexafluoropropylene)-TiO2-Al2O3 as hydrophilic hydrophobic layers, complementing high reflectivity directional water transport well promising moisture capabilities. The architecture possessed excellent (93%) emissivity (∼0.95). In conditions under direct sunlight, the shown reduce skin temperature by 15 °C compared cotton textile. Furthermore, exhibited subambient capacity 5 at noon 2 nighttime. This provides pathway development nanofabrics integrated sweat/moisture management, enabling technologies heat control daily life.

Abstract Thermal management plays an indispensable role in the ever‐emerging flexible electronics, as undercooling or overheating can severely impact their performance and longevity. There is growing interest zero‐energy thermal skins for electronics. The unidirectional cooling effect of radiative exacerbate burden heating electronics cold environments. Temperature‐responsive, self‐adaptive thermoregulated sheets leveraging Fabry‐Pérot cavities exhibit limited flexibility, rendering them unsuitable Their single‐resonator design with a fixed cavity length also limits long‐wave infrared (LWIR) emissivity (ɛ) regulation efficiency (Δɛ) spectral coverage. Extending this to multi‐resonator configurations on 3D fabric's nanofibers has potential enhance Δɛ coverage, which remains challenging. A temperature‐responsive metafabric featuring nanofibrous resonators reported first time, achieving up 0.69, ɛ 0.85 at hot temperatures 0.16 temperatures, while regulating visible (VIS) near‐IR (NIR) light from solar irradiation, thereby enabling thermoregulation. multi‐fibrous resonator system offers 5.6‐fold increase 3.8‐fold broader coverage compared single fibrous resonator. This passive VIS‐NIR‐LWIR eco‐friendly solution thermoregulation under fluctuating temperatures.

Abstract Passive daytime radiative cooling (PDRC) achieves by simultaneously reflecting sunlight and radiating heat to outer space, without consuming any external energy. Traditional PDRC designs use organic materials that are prone aging secondary pollution under solar illumination. Here, a flexible alumina fiber membrane (FAFM) is prepared using electrospinning technology. The fiber‐membrane hierarchical structure ensures macroscopic flexibility, allowing this inorganic material be assembled on complex surfaces just like materials. It can efficiently dissipate emitting infrared radiation matches the atmospheric window scattering sunlight. Importantly, it notable no phenomenon occurs even prolonged ultraviolet irradiation, which brings additional benefits its green energy‐saving properties. As result, outstanding fire resistance thermal insulation prevent possibility of spontaneous combustion in extremely hot weather during summer may serve as multifunctional layer for buildings. This preparation method promotes surface design based more structural future, enabling low‐cost, highly
