Abstract

Cotton is a renewable bio-resource widely employed in human thermal management. However, it is required to further improve its cooling ability to address global warming issues posing serious threats to human activities. Herein, metacotton was produced by applying silica (SiO2)/poly(vinylidene fluoride-hexafluoropropylene) composite aerogel onto the cotton surface via microstructure finishing using the traditional textile equipment. Next, scalable metacotton fabrics with passive radiative cooling effect were obtained by weaving. The aerogel microstructure of metacotton results in excellent passive cooling capability of the fabric and endows it with superhydrophobic, insulating, and breathing properties. The metacotton fabric realizes an average cooling of 8.8 °C during summer days, showing superior cooling performance compared to the standard cotton. Notably, the metacotton fabric exhibits superhydrophobic stain-removal and wash-resistant properties, enhancing passive cooling durability. Furthermore, the method used for fabricating metacotton in this study can be applied to other fibers as well, and it is scalable and adaptable across the conventional equipment, which broadens the thermal management range in the textile industry.

Graphical Abstract

可扩展和可持续的超疏水冷却棉
棉花是一种可再生的生物资源,广泛应用于人体热管理。然而,需要进一步提高其冷却能力,以应对对人类活动构成严重威胁的全球变暖问题。本文采用传统纺织设备将二氧化硅(SiO2)/聚偏氟乙烯-六氟丙烯复合气凝胶涂覆在棉花表面,经微结构整理后制成偏棉。然后,通过织造得到具有被动辐射冷却效果的可伸缩棉织物。超棉的气凝胶结构使织物具有优异的被动冷却性能,并具有超疏水、绝缘和呼吸性能。超棉面料在夏季平均降温8.8°C,与标准棉相比,具有优越的降温性能。值得注意的是,超棉织物具有超疏水性和耐洗涤性能,增强了被动冷却的耐久性。此外,本研究中用于制造超棉的方法也可以应用于其他纤维,并且它在传统设备上具有可扩展性和适应性,从而拓宽了纺织工业的热管理范围。图形抽象
