Schematic illustrating the primary ways of heat dissipation in the human body

Caption

Electrostatic spinning produced an asymmetrically wettable polylactic acid/boron nitride nanosheets (PLA/BNNS) composite fabric that integrates passive radiative cooling, high thermal conductivity (0.38 W·m⁻¹·K⁻¹), and directional moisture transport. Featuring 96% solar reflectance, 93% infrared emissivity, and a sweat evaporation rate of 1.67 g/h, the fabric effectively lowers skin temperature by 2.0°C during the day and 3.8°C at night. This innovative design marks a significant advancement in personal thermal management, particularly in extreme outdoor environments.
