Abstract

The maintenance of a comparatively stable human body temperature through heating is essential for numerous physiological activities. However, the majority of the existing heating strategies are inefficient and wasteful in terms of energy usage, while also falling short in sufficiently protecting the human body against environmental hazards. Fabrics possessed the abilities to retain heat, repel water, and permit moisture to travel through are in high demand, which are essential for energy conservation and protective purposes. Herein, we introduce a highly efficient approach for producing electrospun membranes that exhibit excellent properties of heat confinement, water repellency, and moisture release properties, achieved by incorporating SiO₂ aerogel fillers into interconnected nanofibers. As a result, the obtained aerogel filler incorporation membrane (AFIM) composed of PVDF@SiO₂ exhibited a reduced thermal conductivity and reinforced moisture-release capability, leading to a 2 °C increase in temperature differential over its cotton counterpart and a water vapor transmission rate (WVTR) of 26.83 kg•m⁻²day⁻¹. This work offers insights into the advancement of the thermoregulatory textiles to conserve energy and prevent waterlogging in future challenging conditions. © 2024 Elsevier Ltd
