摘要:

傳統節能窗僅對太陽能（如陽光控制型）、熱輻射（如Low-E玻璃）或者熱對流（如中空玻璃）起阻隔作用，智能節能窗則可以在特定刺激下（環境溫度、電場、氣體、光照變化等）自主調節自身光譜透反射特性，從而機敏地調整進入室內的太陽能或者熱量，實現更高效的節能。作為智能節能窗的核心，變色節能材料可分為有機和無機變色材料。相對于有機材料，無機變色材料具有抗老化性能強、變色持續時間長、熱穩定性能好等優點，是目前主要的智能節能窗材料。本文介紹了最常見的四種無機變色(熱致變色、電致變色、氣質變色和光致變色)材料，包括其發展歷史、節能原理或者變色機理、主要制備工藝和目前存在的問題或者研究現狀等，并就各種智能的發展趨勢進行了展望。

Abstract:

Tranditional energy-saving windows work just by blocking solar energy (solar control coated glass), thermal radiation (Low-E glass) or thermal convection (hollow glass), while smart energy-saving windows could change their optical performances under a given stimulus such as temperature, electrical filed, gas, and light irradiation, et. al., which would endue them the ability to control the heat enter house, bringing higher energy-saving efficiency. Chromic materials is the core of smart energy-saving windows, including organic and inorganic materials. Compare to organic ones, inorganic chromic materials show advantages in age resistance, stability metachrosis and thermal stability, is the main materials of current smart energy-saving windows. This paper reviews the research progress of four sorts of inorganic materials (thermochromic, electricochromic, gasochromic and photochromic), including their development, preparation technology, mechanism of discoloration or energy-saving, current problem and their prospects.
