Smart textile with IR radiative cooling is of paramount importance for reducing energy consumption and improving the thermal comfort of individuals. However, wearable textile via facile methods for indoor/outdoor thermal management is still challenging. Here we present a novel simple, yet effective method for versatile thermal management via silver-coated polyamide (PA) textile. Infrared transmittance of coated fabric is greatly enhanced by 150% due to the multi-order reflection of silver coating. Based on their IR radiative cooling, indoors and outdoors, the skin surface temperature is lower by 1.1 and 0.9 °C than normal PA cloth, allowing the textile to be used in multiple environments. Moreover, the coated fabric is capable of active warming up under low voltage, which can be used in low-temperature conditions. These promising results exemplify the practicability of using silver-coated textile as a personal thermal management cloth in versatile environments.
具有红外辐射冷却功能的智能纺织品对于降低能源消耗和提高个人热舒适度至关重要。然而，通过简便方法实现可穿戴纺织品的室内/室外热管理仍然具有挑战性。在此，我们展示了一种通过镀银聚酰胺（PA）纺织品实现多功能热管理的新颖且有效的简单方法。由于银涂层的多阶反射，涂层织物的红外透过率大幅提高了150%。基于其在室内和室外的红外辐射冷却，皮肤表面温度比普通PA布低1.1℃和0.9℃，使得该纺织品可在多种环境中使用。此外，涂层织物能够在低电压下主动升温，可用于低温条件。这些令人鼓舞的结果例证了在多种环境中将镀银纺织品用作个人热管理布料的实用性。
