High temperature and humidity conditions can lead to metabolic disorders in the human body, equipment corrosion, bacterial growth. Therefore, development of efficient, reusable, biofriendly dehumidifying materials is urgently needed. For this purpose, we developed a humidity-sensitive polyacrylamide composite hydrogel film aimed at effectively regulating skin surface temperature, which enhanced comfort thermal safety high-temperature environments. Comprising poly(vinyl alcohol), poly(ethylene glycol), loaded hygroscopic salt (LiCl), three-dimensional network-structured facilitated rapid evaporation absorbed moisture dissipate excess heat. Herein, phase change material polyethylene glycol was incorporated as storage medium for efficient heat regulation release. This could achieve absorption about 722.1 g m–2 an external 50 °C 90% RH. After conducting 15 absorption–desorption experiments 20 cyclic tensile tests, demonstrated remarkable stability reusability. Furthermore, arm covered with be reduced by 2.2 when it utilized direct sunlight. Due low-cost, straightforward manufacturing processes, reusability, offers promising strategy various applications confronting significant discomfort stress.

Personal protective clothing is essential in biochemical threat environments, however balancing protection, thermal comfort, and breathability remains a significant challenge. This work introduces novel, skin-friendly ultrabreathable radiative cooling membrane (Ub-RCPM), which developed via one-step evaporation-induced pore formation process. The sequential evaporation of solvent nonsolvent during the process endows an open-cell hierarchical structure. By adjusting size, Ub-RCPM simultaneously offers high moisture permeability, passive cooling. structure demonstrates sunlight reflectivity 94.79% infrared emissivity 94.53% through atmospheric window, enables efficient Its water vapor transmission rate 8904.59 g m-2 day-1, 3.5 times higher than that commercial protection clothing.
