In order to address the requirements for warmth and energy conservation in cold climates, the development of personal thermal management textiles that regulate local human thermal comfort has emerged as a promising solution in recent times. Nevertheless, existing warming textile strategies often rely on a singular energy source, exhibit inadequate air/moisture permeability, and lack adaptability to dynamic and intricate climate variations. Herein, a novel multienergy-coupled radiative warming Janus textile has been effectively designed and fabricated via screen printing and foam finishing. Taking advantage of the synergistic effects of directional water transport capability of polyester-covered cotton (with a directional water-transport index of = 577.5%), high mid-infrared radiant reflection (at 60%), electrothermal conversion of copper coating (with a sheet resistance of 0.01 Ω s), and strong solar absorption of the nanoporous structure TA@APTES@Fe(III)@CNT (TAFC) coating (at 98.5%), the Janus fabric exhibits exceptional performance in expelling out one-way sweat/moisture ( = 329.3%) and solar heating (86.9 °C)/Joule heating (226.4 °C at 3.0 V)/heat retention (2.4 °C higher than that of cotton fabric). Furthermore, the fabric is also provided with exceptional mechanical, washing, flame-retardant, and antibacterial performance. This research holds the potential to revolutionize the development and production of warming textiles by incorporating desirable sweat/moisture permeability and multienergy-coupled heating.
为了满足寒冷气候下对保暖和节能的要求，近年来，开发能够调节人体局部热舒适度的个人热管理纺织品已成为一种很有前景的解决方案。然而，现有的保暖纺织品策略通常依赖单一能源，空气/湿气渗透性不足，且缺乏对动态复杂气候变化的适应性。在此，通过丝网印刷和泡沫整理有效设计并制备了一种新型的多能量耦合辐射保暖双面织物。利用聚酯包覆棉的定向输水能力（定向输水指数为577.5%）、高的中红外辐射反射率（60%）、铜涂层的电热转换（表面电阻为0.01Ω·s）以及纳米多孔结构TA@APTES@Fe(III)@CNT（TAFC）涂层的强太阳能吸收（98.5%）的协同效应，该双面织物在单向排汗/湿气（329.3%）和太阳能加热（86.9℃）/焦耳加热（3.0V时为226.4℃）/保温（比棉织物高2.4℃）方面表现出优异性能。此外，该织物还具有优异的机械性能、洗涤性能、阻燃性能和抗菌性能。这项研究通过引入理想的汗液/湿气渗透性和多能量耦合加热，有可能彻底改变保暖纺织品的开发和生产。
