摘　　要：能源枯竭问题已经成为人类社会可持续发展的阻碍。据统计,建筑能耗约占我国能源消费总量的20%,因此通过调控太阳光辐射和物体红外热辐射来进行智能光热管理,达到自适应环境温度和降低能耗的目的,具有重大的意义。本文综述了近年来仿生光热管理智能高分子材料的重要研究进展,包括具有温度自适应特性的太阳光辐射动态调控和红外热辐射动态调控的智能高分子材料。首先介绍了具有温度自适应特性的液晶和水凝胶材料在太阳光辐射动态调控方面的应用,然后介绍了在中长红外波段具有可调发射率的红外热辐射动态调控高分子材料。最后,讨论了仿生光热管理智能高分子材料在未来发展和潜在应用方面的机遇和挑战。The problem of energy depletion has become an obstacle to the sustainable development of human society.According to statistics,Chinese building energy consumption accounts for 20%of our total energy consumption.Therefore,it is of paramount importance to intelligently manage the solar radiation and infrared thermal radiation of objects,achieving the self-adaption of environmental temperature while reducing energy consumption.This work summarizes the state-of-the-art advancements of bioinspired intelligent polymer materials for optical and thermal management,which includes temperature-adaptive polymer materials with dynamic modulation of solar radiation and infrared thermal radiation.The temperature-adaptive polymer materials including liquid crystals and hydrogels for dynamic modulation of solar radiation are introduced firstly,then the advanced polymer materials with tunable emissivity in the mid-wavelength and long-wavelength infrared spectral range are illustrated for dynamic modulation of infrared thermal radiation.This review concludes with a perspective on the opportunities and challenges for the future development and potential applications of emerging bioinspired intelligent polymer materials for optical and thermal management.
