摘　　要：广泛采用的低辐射(Low-E)镀膜玻璃窗节能效果良好,但不具备太阳得热动态调节功能。相比于太阳得热静态不可调窗,在制冷季低得热、采暖季高得热的智能可调透明围护结构更加节能。介绍了一种在聚二甲基硅氧烷弹性体上镶嵌3层纳米功能层的膜材料,可用于制备太阳得热可智能动态调节的透明建筑围护结构,提高建筑节能与舒适性。智能动态调节膜可以实现直接的太阳透射率调节。通过建筑能耗模拟证实,由该智能动态调节膜制备的智能窗对比传统的太阳得热静态不可调窗,在全国范围内可实现2.4%~13.8%的暖通空调系统节能。Although the widely-adopted low-emissivity window demonstrates favorable energy-saving effects,it lacks the ability to regulate solar heat gain.Compared to the solar heat gain non-adjustable static windows,the intelligent adjustable transparent enclosure structure with low heat gain during the cooling season and high heat gain during the heating season is more energy-efficient.This paper introduces a novel film material comprising three nano-functional layers embedded with Polydimethylsiloxane polymer elastomers to prepare transparent building envelope structure that can intelligently and dynamically adjust solar heat gain,improving building energy efficiency and comfort.The intelligent dynamic adjustment film can achieve a wide range of direct solar transmittance adjustment.The energy-efficiency of this intelligent window has been validated through building energy consumption simulation,showing a significant HVAC system energy savings range of 2.4%to 13.8%around China compared to traditional solar heat gain non-adjustable static windows.
