摘要
光和热是自然界最普遍的两种能量形式,通过对光的调控而实现对热的管理,是能源、环境、航空航天、军事防护等领域常用的被动式热管理手段。微纳多孔聚合物由于其独特的尺度和形貌可以实现对特定波长入射光的强反射,再借助聚合物自身官能团在中红外波段的本征吸收而表现出选择性红外辐射/透射特征,可以在较宽波段范围内发挥有效的光热调控功能,并且因为原材料成本低廉、制备方法简单、具备卷对卷规模化生产潜力及良好的耐候性和力学性能,而备受研究人员关注。本文以辐射冷却应用为背景,概述了微纳多孔聚合物材料的制备及形貌调控方法,在此基础上综述了多孔聚合物辐射冷却性能调控的相关研究成果,并进一步阐述了微纳多孔聚合物在辐射冷却领域的应用,最后对其存在的问题及未来的发展方向进行了总结和展望。
Light and heat are the two most common energy forms in nature.Heat management realized by spectral regulation is a passive thermal management method commonly used in the fields of energy,environment,aerospace,military protection and so on.Owing to its unique scale and morphology,micro/nano-porous polymer can achieve high reflectance of incident light with specific wavelength,and with the selective radiation/transmittance by the intrinsic absorption of functional groups in the mid-infrared waveband,it can realize effective photothermal regulation in a wide waveband range.Moreover,micro/nano-porous polymer has attracted much attention of researchers on account of the low cost of raw materials,convenient fabrication,large-scale roll-to-roll production potential and good weather resistance and mechanical properties.Based on the application of radiative cooling as the background,this article introduces the preparation and morphology control methods of micro/nano-porous polymer,and on this basis,reviews the relevant research results of radiative cooling performance control of porous polymer and further expounds the application of porous polymer in the field of radiative cooling.Finally,this article summerizes the existing problems and prospects the future development.
