Silver coated textile for versatile personal thermal management via multi-order reflections
Abstract Personal thermal management (PTM) is of paramount importance for reducing energy consumption and improving the thermal comfort of individuals. However, wearable textile via facile methods for indoor/outdoor PTM is still challenging. Here we present a novel simple yet effective method for versatile PTM via silver coated 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, in indoor and outdoor, the skin surface temperature is lower by 1.1˚C and 0.9˚C than normal 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.
