Thermochromic window assembly based on Bragg reflector structure and preparation method
The invention provides a thermochromism window assembly based on a Bragg reflector structure. The thermochromism window assembly comprises a glass substrate, a Bragg reflector structure layer compounded on the surface of the glass substrate, and a thermochromism layer compounded on the surface of the Bragg reflector structure layer. The Bragg reflector structure layer is composed of titanium dioxide layers and silicon dioxide layers which are alternately stacked. The thermochromic layer comprises a plurality of stacked nanowire films, and each nanowire film comprises tungsten-doped vanadium dioxide nanowires which are orderly arranged in the same direction. According to the invention, the limitation of dynamic modulation of solar radiation is realized, the indoor temperature is effectively reduced in summer, the indoor requirement on solar radiation energy incidence can be met in winter, the indoor temperature is maintained, and meanwhile, the high transmittance of visible light is maintained, so that an indoor environment suitable for living is created. The invention further provides a preparation method of the thermochromic window assembly based on the Bragg reflector structure.
本发明提供了一种基于布拉格反射器结构的热致变色窗户组件，包括玻璃基底，复合在所述玻璃基底表面的布拉格反射器结构层，和复合在所述布拉格反射器结构层表面的热致变色层；所述布拉格反射器结构层为交替层叠的二氧化钛层和二氧化硅层；所述热致变色层包括多个层叠的纳米线薄膜，所述纳米线薄膜包括同向有序排列的钨掺杂的二氧化钒纳米线。本发明实现太阳辐射动态调制的限制，夏天有效降低室内温度，冬季又能满足室内对太阳辐射能量射入的需要，维持室内温度，同时保持对可见光的高透过率，从而营造适宜居住的室内环境。本发明还提供了一种基于布拉格反射器结构的热致变色窗户组件的制备方法。
