Heating requirements for residential and commercial dwellings result in significant energy consumption and deleterious environmental effects. Personal radiative thermal management textiles regulate the wearer’s body temperature by controlling the material’s intrinsic optical properties. Passive heating textiles suppress radiative heat losses and therefore significantly reduce the energy consumption required for building heating systems. Guided by an optical theoretical approach, a transparent radiation shield (TRS) is designed based on silver nanowires (AgNWs) that can suppress human body heat with simultaneous visible light transmittance anticipated for practical fabrics. We experimentally demonstrated a TRS with large infrared light reflectance (low emissivity of 35%) and a visible (VIS) transparency value of 75% (400–800 nm). The results are well corroborated by the Mie scattering theory and the wire-mesh equivalent sheet impedance model, which provide fundamental mechanism understanding and guidance toward higher performance. The TRS is fabricated by a simple, solution-processing method with thermoplastic elastomer protective layers, granting notable stretching capabilities, mechanical robustness, and conformability to any body shape or object. The rigorous theoretical strategy enables the scalable synthesis of low-emissivity and visibly transparent textiles for personal thermal comfort.

用于可穿戴透明热辐射屏蔽的溶液处理金属纳米线网络


住宅和商业住宅的供暖要求导致大量能源消耗和有害的环境影响。个人辐射热管理纺织品通过控制材料的固有光学特性来调节穿着者的体温。被动加热纺织品可抑制辐射热损失，从而显着降低建筑供暖系统所需的能耗。在光学理论方法的指导下，基于银纳米线（AgNW）设计了一种透明辐射屏蔽（TRS），它可以抑制人体热量，同时具有实际织物预期的可见光透射率。我们通过实验证明了 TRS 具有较大的红外光反射率（发射率低至 35%）和可见光 (VIS) 透明度值为 75%（400–800 nm）。米氏散射理论和线网等效片阻抗模型很好地证实了该结果，为理解更高的性能提供了基本的机制和指导。 TRS 采用简单的溶液加工方法制成，具有热塑性弹性体保护层，具有显着的拉伸能力、机械坚固性以及对任何身体形状或物体的适应性。严格的理论策略使得低发射率和可见透明纺织品的可扩展合成成为可能，以实现个人热舒适。
