Abstract Radiative cooling fabric creates a thermally comfortable environment without energy input, providing sustainable approach to personal thermal management. However, most currently reported fabrics mainly focus on outdoor cooling, ignoring achieve simultaneous both indoors and outdoors, thereby weakening the overall performance. Herein, full-scale structure with selective emission properties is constructed for indoor cooling. The achieves 94% reflectance performance in sunlight band (0.3–2.5 µm) 6% mid-infrared (2.5–25 µm), effectively minimizing heat absorption radiation release obstruction. It also demonstrates 81% radiative atmospheric window (8–13 25% transmission μm), 60 26 W m −2 net power outdoors indoors. In practical applications, excellent human temperatures 1.4–5.5 °C lower than typical polydimethylsiloxane film. This work proposes novel design advanced fabric, offering significant potential realize

Passive radiative cooling technology provides a sustainable thermal management strategy for outdoor workers under extremely hot environments. However, daytime textiles typically appear white or mirror-like due to the near-complete reflection of sunlight, which poses significant limitation applications where visual aesthetics are important. Herein, we designed colored photoluminescent (CPRC) metafabrics, woven from carbon-dot-based coaxial porous fibers, achieve effective without sacrificing color aesthetics. The fibers with nanostructured light-scattering shell layer and an enhanced mid-infrared emission core layer, together improve sunlight human infrared radiation. Leveraging properties carbon dots, CPRC metafabrics enable selective adsorption visible light display vivid colors while re-emitting photons reduce solar heat generation, achieving high light-to-photon conversion efficiency 48.3%. Consequently, metafabric its colorful appearance demonstrates maximum net power 69.2 W m-2, offering average temperatures that 3.7 3.6 °C lower than those commercial wool dye-based fabric, respectively. Furthermore, possess self-sensing health monitoring capability long-time durability, ensuring both safety comfort workers. This work effectively addresses long-standing problem integrating textiles, facilitating development application next-generation wearable energy-saving textiles.

Passive radiative cooling materials are widely recognized as attractive innovations for reducing emissions and expanding life-saving access. Despite immense research attention, the adoption of such technologies is limited largely due to a lack scalability cost compatibility with market needs. While paint coating-based approaches offer more sensible solution, many demonstrations suffer from issues low solar reflectance performance or material sustainability use harmful solvents. In this work, we demonstrate passive which achieves an extremely high value 98% using completely water-based formulation. Material promoted by incorporating size-dispersed calcium phosphate biomaterials, broadband reflectance, well self-crosslinking binder, providing water resistance durability without introducing materials. Common industry pigments integrated within binder comparison, illustrating benefit finely-tuned particle size distributions even in low-refractive-index phosphates. With scalability, outdoor durability, eco-friendly materials, demonstrated offers practical approach exacerbating other environmental issues.

The materials efficiently emitting photoluminescence (PL) under solar irradiation could find broad applications in passive radiative cooling of buildings, urban heat mitigation, and energy harvesting. In this work, we discuss the limitations common laboratory characterization such (using tunable light sources or simulators) propose a methodology for direct outdoor PL efficiency full irradiation. A simple, portable radiometry setup with an integrating sphere is described, its capability rapid determination spectral distribution absorbed emitted power, as well overall power quantum yield, demonstrated. By three developed daytime applications, reveal deviations obtained parameters caused by replacement real that simulators. described method suitable studies long-term stability, photo-induced degradation, thermal effects.
