Due to global warming and the energy crisis, incorporating passive radiative cooling into personal thermal management has attracted extensive attention. However, developing a wearable textile that reflects incoming sunlight and allows mid-infrared radiation transmission is still a tough challenge. Herein, a shish-kebab superstructure film was produced via a flow-induced crystallization strategy for personal radiative cooling. The resulting film endowed a high infrared transmittance (87%) and improved sunlight reflectivity (83%). A device was developed to simulate the human body skin, and the temperatures of the shish-kebab film were 2.5 and 2.6 °C lower than that of traditional textile in outdoor and indoor tests, respectively. In order to make the shish-kebab film more wearable, a series of modifications were then carried out. This study demonstrates the substantial potential to personal thermal management textiles.
由于全球变暖和能源危机，将被动辐射冷却纳入个人热管理已引起广泛关注。然而，开发一种能反射入射阳光并允许中红外辐射传输的可穿戴纺织品仍然是一项艰巨的挑战。在此，通过流动诱导结晶策略制备了一种用于个人辐射冷却的串珠超结构薄膜。所得薄膜具有高红外透过率（87%）和提高的阳光反射率（83%）。开发了一种模拟人体皮肤的装置，在室外和室内测试中，串珠薄膜的温度分别比传统纺织品低2.5和2.6摄氏度。为了使串珠薄膜更具可穿戴性，随后进行了一系列改性。这项研究证明了个人热管理纺织品具有巨大潜力。
