Flexible Radiative Cooling Textiles for Practical Implementation

ABSTRACT

Passive daytime radiative cooling (PDRC) technology, which can emit surface heat into outer space through the atmospheric transparency window, offers a novel solution for addressing energy shortages because it requires no external energy input. In the past, researchers have made strides in PDRC materials, but they fall short in terms of flexibility, posing a hindrance to their practical implementation for multiply curved radiative cooling. Textiles, characterized by their porous structures and high aspect‐ratio fibers, offer better softness and breathability compared to coatings and films, presenting considerable promise as a compelling platform for flexible radiative cooling applications. However, research on flexible radiative cooling textiles (FRCTs) is relatively limited and still faces many technical challenges. Based on radiative cooling technology, this review provides a comprehensive analysis of various FRCTs, with a primary focus on summarizing their practical implementation in areas such as personal thermal management, vehicle cabin cooling, and outdoor equipment cooling.
