Cooling Textiles Provide a New Solution to Urban Heat Islands

Abstract

Radiative cooling textiles offer significant potential for enhancing personal thermal comfort amid rising global temperatures. Recently, a spectrally selective hierarchical fabric was reported to emit predominantly within the atmospheric transmission window while suppressing parasitic heat from the surrounding infrastructure, thus combating the urban heat islands. This development represents a significant advance in personal thermal management, demonstrating the potential of radiative cooling fabrics to adapt to various environmental conditions.
