Abstract

Despite millennia of use, conventional cotton textiles remain challenged by inefficient perspiration management. Inspired by the skin surface structure of a desert lizard, we propose an integrated thermal-wet comfort (i-TWC) textile featuring a gradient wetting structure. The design of the sweat gland-like sweat-wicking channel endows the i-TWC textile with an impressive 2 s one-way sweat transfer capability. Meanwhile, the introduction of a triboelectric field accelerates the evaporation of perspiration in the hydrophilic layer, ensuring the stability of the one-way water transfer. It is worth noting that the synergistic effects of the bioinspired sweat gland structure and triboelectric field result in a significantly improved evaporation rate (increased from 0.17 to 0.33 g h-1) and show some potential for passive cooling of the human body (1.07 °C). This work offers valuable insights for personal moisture management fabric with directional transport ability, promising advancements in the field of thermal-wet comfort textiles.

集成热湿舒适纺织品的生物灵感汗运输和摩擦电蒸发个人排汗管理。

尽管使用了几千年，传统的棉织品仍然面临着效率低下的汗水管理的挑战。受沙漠蜥蜴皮肤表面结构的启发，我们提出了一种具有梯度润湿结构的综合热湿舒适（i-TWC）纺织品。类似汗腺的排汗通道设计赋予了i-TWC纺织品令人印象深刻的2 s单向排汗能力。同时，摩擦电场的引入加速了亲水层中汗液的蒸发，保证了单向水传递的稳定性。值得注意的是，仿生汗腺结构和摩擦电场的协同作用显著提高了蒸发速率（从0.17 g h-1增加到0.33 g h-1），并显示出对人体（1.07°C）进行被动冷却的潜力。这项工作为具有定向输送能力的个人水分管理织物提供了有价值的见解，在热湿舒适纺织品领域有希望取得进展。
