Due to global warming and the energy crisis, incorporating passive radiative cooling into personal thermal management has attracted extensive attention. However, developing a wearable textile that reflects incoming sunlight and allows mid-infrared radiation transmission is still a tough challenge. Herein, a shish-kebab superstructure film was produced via a flow-induced crystallization strategy for personal radiative cooling. The resulting film endowed a high infrared transmittance (87%) and improved sunlight reflectivity (83%). A device was developed to simulate the human body skin, and the temperatures of the shish-kebab film were 2.5 and 2.6 °C lower than that of traditional textile in outdoor and indoor tests, respectively. In order to make the shish-kebab film more wearable, a series of modifications were then carried out. This study demonstrates the substantial potential to personal thermal management textiles.

Space cooling and heating consume a large proportion of global energy, so passive thermal management materials (i.e., without energy input), especially dual-mode materials including cooling and heating bifunctions, are becoming more and more attractive in many areas. Herein, a function-switchable Janus membrane between cooling and heating consisting of a multilayer structure of polyvinylidene fluoride nanofiber/zinc oxide nanosheet/carbon nanotube/Ag nanowire/polydimethylsiloxane was fabricated for comprehensive thermal management applications. In the cooling mode, the high thermal radiation emissivity (89.2%) and sunlight reflectivity (90.6%) of the Janus membrane resulted in huge temperature drops of 8.2–12.6, 9.0–14.0, and 10.9 °C for a substrate, a closed space, and a semiclosed space, respectively. When switching to the heating mode, temperature rises of 3.8–4.6, 4.0–4.8, and 12.5 °C for the substrate, closed space, and semiclosed space, respectively, were achieved owing to the high thermal radiation reflectivity (89.5%) and sunlight absorptivity (74.1%) of the membrane. Besides, the Janus membrane has outstanding comprehensive properties of the membrane, including infrared camouflaging/disguising, electromagnetic shielding (53.1 dB), solvent tolerance, waterproof properties, and high flexibility, which endow the membrane with promising application prospects.

Intense heat waves pose a serious threat to public health and well-being, especially in outdoor spaces. Outdoor high-temperature environments without air conditioners are major challenges for humanity. However, an achievable approach that can provide outdoor cooling without consuming any energy is lacking. Hence, this work presents a novel hierarchical fabric emitter (HFET) used for sunshade sheds to provide radiative outdoor cooling for humanity, the HFET is composed of polyethylene/silicon dioxide/silicon nitride film, melt-blown polypropylene film, and polydimethylsiloxane film from top to bottom. In addition to reflecting 94% solar irradiance by its top surface, the HFET shows selective emission (0.82 in the atmospheric window and 0.38 outside the atmospheric window) on its top surface to outer space and broadband absorption (0.80 in the longwave infrared band) on its bottom surface from the inside. This bidirectional asymmetric emission enables the simulated skin to avoid overheating by 2–11 °C relative to the reverse HFET and bare cases under direct sunlight. Due to its excellent cooling capability, the HFET will be one of the most considerable solutions for outdoor cooling in hot summer environments. Graphical Abstract

Passive daytime radiative cooling (PDRC) technique is desirable for outdoor application as it can cool objects without energy consumption. In this work, a polydimethylsiloxane (PDMS) film incorporated with Kaolin particles was fabricated by a simple and low-cost method. Integrating with high sunlight reflectance and great thermal emissivity, the sample displayed a remarkable PDRC property by yielding an average temperature drop of 12.8℃ compared to the sub-ambient temperature. Additionally, the superhydrophobicity of the sample enabled the surface of the sample free-contamination after water rinse. The superhydrophobic properties can be maintained even after 60 days of UV light continuous exposure.

Radiative cooling textiles are cooled by transferring the body’s metabolic heat to outer space and reflecting sunlight, without any energy input, providing a sustainable way for personal thermal management (PTM). However, current research on the environmental adaptability of fabrics is very scarce, and most of the research on PTM has a single application environment. Here, based on the Mie scattering theory and the design of micronanostructures, this work demonstrates an environmentally adaptive fabric (EAF) composed of polyformaldehyde (POM) with a high selectivity ratio and hollow SiO2. It not only achieves the selective emission of the atmospheric window (8–13 μm) but also shows the transmission of the entire band (2.5–25 μm) and reflect sunlight (0.3–2.5 μm). Remarkably, its optical properties remain outstanding after being subjected to acid, alkaline, and UV treatments, which match the daily garment use application requirements. As a result, the EAF achieves efficient radiative cooling both outdoors (under sunny and cloudy conditions) and indoors (1.5–12.2 °C lower than cotton and commercial cooling fabrics). The EAF with excellent environmental adaptability and robustness brings new possibilities for the rational design of next-generation smart thermal management textiles and other sustainable applications.
