摘要

Intense physical activity in under high summer temperatures is accompanied by leads to excessive perspiration, while solar ultraviolet (UV) radiation inflicts additional skin damage, rendering conventional textiles insufficient to meet human skin comfort requirements for ensuring thermal comfort and UV protection. This study introduces a novel bilayer membrane comprising aluminium-doped zinc oxide@cellulose acetate/polylactic acid (AZO@CA/PLA), fabricated through magnetron sputtering and coupled with electrospinning. The membrane synergistically integrates radiative cooling, UV shielding, and directional moisture transport properties functionalities. The incorporation of AZO significantly enhances UV absorption, endowing the membrane with excellent superior UV-protective capabilities. An asymmetric wettability architecture composed consisting of a hydrophobic PLA layer and a hydrophilic AZO@CA layer enabled facilitates unidirectional sweat transport, establishing a favorable moisture-comfort environment. The membrane exhibits a high solar reflectance of 96.7% and mid-infrared (MIR) emissivity of 97.2%, achieving a temperature reduction of 6.4 °C under direct sunlight. Finite-difference time-domain (FDTD) simulations and infrared thermography further validate its exceptional solar scattering and MIR radiative properties. Additionally, the membrane possessed demonstrates excellent air permeability, mechanical strength, and flexibility. This work successfully amalgamates the essential attributes required for advanced wearable textiles, underscoring the potential of the AZO@CA/PLA membrane for practical deployment in high-temperature summer environments.
