摘要

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 suc-cessfully 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 win-dow (wavelength:8 ＜ λ ＜ 13 μm),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.
