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

The development of multifunctional cooling textiles has become crucial in addressing global warming and the increasing need for personal thermal management. Developing with integrated unidirectional moisture transport radiative functionalities through a simple fabrication method critical challenge management under high-temperature conditions. This study presents moisture-wicking textile (RCUM-Textile) one-step phase separation method. By employing evaporation-induced (EIPS) non-solvent-induced (NIPS) mechanisms, RCUM-Textile achieves trilayer structure comprising hydrophobic SiO2/PVDF-HFP upper layer hydrophilic cotton lower layer. innovative integrates efficient sweat evaporation, enabling solar reflectance 89.7%, mid-infrared emissivity 94.9%, effect 8.7°C direct sunlight. solution, utilized as finishing agent, simplifies functionalization process, ensuring uniform coating structural stability while reducing processing complexity. Additionally, its enhanced evaporation rate (0.029 g·m-2·s-1) reduced enthalpy (2084 J/g) significantly improve regulation wearer comfort. provides cost-effective practical approach to fabricating high-performance textiles, paving way applications devices, wearable electronics, industrial-scale systems.

Abstract Energy consumption for buildings and space thermal regulation account ∼20% of global electricity usage. One the key measures to alleviate such energy is functionalizing windows enhance generation reduce temperature expenditures. However, versatile that integrate both harvesting remain scarce. Luminescent solar concentrators (LSCs), which are large‐area photon‐harvesting devices, have demonstrated notable advantages as photovoltaic due their building compatibility, but potential generally overlooked. In this work, temperature‐regulated LSCs (TRLSCs) prepared through high mid‐infrared (MIR) emissive perovskite‐polymer luminescent films low‐MIR‐emissive transparent electrodes. TRLSCs not only enable favorable performance also facilitate by tunable radiative cooling self‐powered heating. Compared conventional glass, internal reduced up 12.0 °C via TRLSCs. Utilizing competitive absorption between electrodes, range can be conveniently modulated from 5.5–12.0 3.9–7.9 flipping TRLSCs, enabling adaptive management. What more, achieved electrodes active This work demonstrates promising future in functionalized zero‐energy buildings.

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.
