Abstract

We present a new approach for designing thermal shielding materials using two-dimensional (2D) oxide nanosheets. Our approach is hetero-assembly design [(Ti0.87O2)m(Cs2.7W11O35−d)20 (m = 0, 5, 10) ] by overlaying high refractive index (n) Ti0.87O2 nanosheets with transparent conducting Cs2.7W11O35−d nanosheets. By a proper design of the thickness of high-n Ti0.87O2 layers, we achieved the optimum thermal shielding properties with a high NIR reflectance (> 46%), a high visible transparency (> 76%) and a neutral color in an ultrathin form (< 60 nm). Our nanosheet approach is of technological importance for exploring new thermal shielding materials.

用于定制热屏蔽材料的二维氧化物纳米片的异构组装设计

我们提出了一种利用二维氧化纳米片设计热屏蔽材料的新方法。我们的方法是通过将高折射率(n) Ti0.87O2纳米片与透明导电的Cs2.7W11O35 - d纳米片叠加在一起，进行异质性组装设计[(Ti0.87O2)m(Cs2.7W11O35 - d)20 (m = 0,5,10)]。通过适当设计高n Ti0.87O2层的厚度，我们获得了最佳的热屏蔽性能，具有高近红外反射率(> 46%)，高可见光透明度(> 76%)和超薄形式(< 60 nm)的中性颜色。我们的纳米片方法对于探索新的热屏蔽材料具有重要的技术意义。
