Promising commercial fabrics with radiative cooling for personal thermal management

用于个人热管理的具有商业化前景的辐射制冷织物

With global warming,the need for cooling is soaring.About 15%of the world’s electricity consumption and 10%of greenhouse gas emissions are due to cooling systems[1],mainly because a large amount of cooling load is used to reduce the temperature of the environment or objects and cannot be efficiently applied to the human body.Therefore,personal thermal management(PTM)as an efficient cooling method has gained widespread attention in recent years[2,3].Researchers from Stanford University have successfully produced nano-polyethylene that can effectively reduce the temperature of the human body fabric[4].However,to ensure a high transmittance of the fabric through the atmospheric window(wavelength:8<λ<13μm),its thickness is limited.The effect of solar heat transfer increases as the thickness of the fabric decreases,so fabrics that can effectively manage human heat remain a challenge.
