A Hierarchically Nanofibrous Self-Cleaning Textile for Efficient Personal Thermal Management in Severe Hot and Cold Environments

“…Meanwhile, the temperatures of the simulated skin covered with the PVB–PDMS side of the HNF textile is 42.9 °C, which is 7.2 and 11.2 °C lower than the one covered with white cotton and bare simulated skin (Figure e, Figure S18b), respectively. Notably, the HNF textile shows superior cooling performance compared to representative textiles reported in the literature (Figure f). ,,,,− This demonstrates that the HNF textile has an excellent cooling capability in high-temperature environments, making it highly possible for effective passive outdoor cooling.…”

“…Obviously, the temperature difference between the PAN-CNT side and black cotton is much greater than that of black cotton/PAN-CNT and black cotton, indicating that the synergistic effect of thermal insulation and radiative heating is better than single radiative heating in low temperature environments. Also, the heating performance of the HNF textile improved significantly, which outperforms the reported radiative heating textiles (Figure e). ,,,,− Additionally, the infrared thermal images of the HNF textile covered on the human arm with the PAN-CNT surface exposed to the outside are displayed in Figure S22. It is clear that surface color of the PAN-CNT side is cooler than that of black cotton, probably because most of the heat cannot be transferred to the upper surface through the HNF textile.…”

Recent advancements in radiative cooling textiles for personal thermal management

“…88,89 It is also sufficient to realize multiple functions and special morphologies by adding functional materials into the spinning precursor solution or adjusting the spinning parameters. 48 Unlike electrospinning that usually delivers a nonwoven fabric, melt spinning extrudes a melted polymer without solvent into bers at a high temperature, which can be subsequently weaved into textiles. 23,47,90 Similarly, in wet spinning, a ne stream is extruded from the spinneret holes into a coagulation bath, forming primary bers for subsequent weaving.…”

Synchronous Radiative Cooling and Thermal Insulation in SiO2/Poly(vinyl alcohol) Composite Aerogel for Energy Savings in Building Thermal Management

“…Currently, there are many approaches to deal with such overcooling, including mechanical flip-switching warming/cooling, − phase change material modulation, , thermochromic hydrogel modulation of solar reflection, − and W-VO 2 based modulation of mid-infrared emission. , However, a mechanical flip requires extra energy, and phase change materials have a limited modulation range of temperature and capability. As for hydrogel, it attenuates overcooling at low temperatures in the daytime while continuing to cool at night.…”
