Sweat passive‐cooling textiles with asymmetric wettabilities on different sides offer an effective and low‐energy consumption solution to personal thermal management in extreme thermal environments. However, the sweat‐wicking and the cooling abilities decrease when the textile is contaminated by low‐surface tension oily liquid fouling. The integration of anti‐oily liquid fouling and sweat‐wicking abilities on textile involves resolving the contradiction between hydrophilic and oleophobic properties and seeking eco‐friendly short‐chain fluorides to reduce the surface energy. Herein, a sustainable oily liquid‐proof passive cooling (SOC) textile for personal thermal management is proposed. The SOC textile is obtained by applying a fluoride‐free hydrophobic coating layer to one side of the high thermal conductive superoleophobic/superhydrophilic basal textile, which is fabricated using eco‐friendly short‐chain fluoride. The SOC textile preserves the anti‐oily liquid fouling property even after 2000 abrasion cycles. Experimental test revealed that the SOC textile exhibits a cooling effect of ≈5 °C compared with the cotton textile, and the up to 70% reduction in sweating rate under the constant metabolic heat production rates. The configuration of the SOC textile would inspire the future design of intelligent textiles for personal thermal management, and the proposed strategy have implications for fabrication of eco‐friendly oil‐water separation materials.

用于个人热管理的可持续油性防液被动冷却 (SOC) 纺织品


不同侧面具有不对称润湿性的汗被动冷却纺织品为极端热环境下的个人热管理提供了有效且低能耗的解决方案。然而，当纺织品被低表面张力油性液体污垢污染时，排汗和冷却能力会降低。将抗油性液体污染和排汗能力结合到纺织品上需要解决亲水性和疏油性之间的矛盾，并寻求环保的短链氟化物来降低表面能。本文提出了一种用于个人热管理的可持续油性防液被动冷却（SOC）纺织品。 SOC纺织品是通过在高导热超疏油/超亲水基础纺织品的一侧涂上无氟疏水涂层而获得的，该基础纺织品是使用环保的短链氟化物制成的。即使经过 2000 次磨损循环后，SOC 织物仍能保持抗油性液体污垢的性能。实验测试表明，与棉纺织品相比，SOC纺织品表现出约5°C的降温效果，在恒定的代谢产热速率下，出汗率降低高达70%。 SOC纺织品的配置将启发用于个人热管理的智能纺织品的未来设计，并且所提出的策略对环保型油水分离材料的制造具有影响。
