辐射制冷织物的制备及其多功能应用进展OA

Passive daytime radiative cooling(PDRC)fabrics exhibit significant potential for efficient personal cooling,leveraging their advantages of zero energy consumption,zero carbon emissions,high cooling efficiency,and environ-mental friendliness.PDRC fabrics effectively reduce skin temperature by reflecting external heat through high solar re-flectivity and by radiating heat from the human body into outer space through high infrared emissivity within the atmo-spheric transparency window.In this review,the fundamental principles,spectral design,material classification,fabrica-tion methods,and performance evaluation of PDRC fabrics are systematically examined,and trends in multifunctional integration are analyzed.Key challenges related to performance trade-offs,service durability,and large-scale industrial-ization are discussed.Finally,prospects for intelligent,eco-friendly and industrial development of PDRC fabrics are outlined,providing theoretical basis and highlighting the potential applications for advancing sustainable personal ther-mal management materials.
