A Shish-Kebab Superstructure\nFilm for Personal Radiative\nCooling

Abstract

Due to global warming and the energy crisis, incorporating\npassive\nradiative cooling into personal thermal management has attracted extensive\nattention. However, developing a wearable textile that reflects incoming\nsunlight and allows mid-infrared radiation transmission is still a\ntough challenge. Herein, a shish-kebab superstructure film was produced\nvia a flow-induced crystallization strategy for personal radiative\ncooling. The resulting film endowed a high infrared transmittance\n(87%) and improved sunlight reflectivity (83%). A device was developed\nto simulate the human body skin, and the temperatures of the shish-kebab\nfilm were 2.5 and 2.6 °C lower than that of traditional textile\nin outdoor and indoor tests, respectively. In order to make the shish-kebab\nfilm more wearable, a series of modifications were then carried out.\nThis study demonstrates the substantial potential to personal thermal\nmanagement textiles.
