A Shish-Kebab Superstructure Film for Personal Radiative Cooling

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 degrees 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.

The development of a wearable textile that reflects incoming sunlight and allows mid-infrared radiation transmission is a tough challenge in the field of personal thermal management. This study presents a shish-kebab superstructure film with high infrared transmittance (87%) and improved sunlight reflectivity (83%) for personal radiative cooling. The film's temperature was significantly lower than that of traditional textiles in outdoor and indoor tests, demonstrating its substantial potential for personal thermal management.
