Radiative cooling textiles dissipate human body heat without any energy input, providing a sustainable means for personal thermal management. However, there is still a lack of textile materials to support efficient cooling in varied outdoor and indoor environments. Here we show a polyoxymethylene (POM) nanotextile design that not only achieves selective emission in the atmospheric window (8–13 μm) but also shows transmission in the remaining mid-infrared wavebands and reflection of sunlight (0.3–2.5 μm). As a result, the POM textile achieves efficient radiative human body cooling both outdoors (under sunny and cloudy conditions) and indoors (0.5–8.8 °C lower than typical textiles). Moreover, the textile design shows favourable wearability and outperforms its commercial counterparts when used as protective clothing. The POM material provides both indoor and outdoor human body cooling and introduces new possibilities in the rational design of next-generation smart textiles and other applications supporting sustainability.

The risk of target exposure increases significantly with the advancement of detection technologies, especially in the visible and near-infrared spectral bands. Hence, there is an urgent need for a material with better environmental similarity. The primary background on the ground is green vegetation, necessitating the development of a material with a color similar to that of leaves. The high-temperature resistance CoAl 2 O 4 Nanofiber Film (CNF) is conducted by electrospinning. The CNF is characterized by colors and spectral curves akin to vegetation in the visible light spectrum, and its spectral performance in the visible and near-infrared range is equivalent to that of CoAl 2 O 4 Nanoparticle Powder (CNP). The color and reflection spectrum of CNF can be controlled through process parameters such as calcination temperature, enabling better environmental integration. Furthermore, CNF can be independently shaped without the involvement of a resin matrix, ensuring its high-temperature stability. This expands the application range of the material in high-temperature and complex environments.
