在这项工作中，BiOClxBr1−xmicroflowers被合成为超疏水近红外反射涂层的基石。Cl与Br的摩尔比对biocclxbr1−x的微观结构和光学性能有很大的影响。随着x值的增大，微花结构由松散向致密转变。BiOClxBr1−的近红外太阳反射率为0.860 ~ 0.935。BiOClxBr1−xcoatings将热箱内部温度降低了约3.9°C。由于BiOClxBr1−xmicroflowers的三维分层结构，超疏水冷涂层可用于各种建筑材料，如混凝土、铝板和玻璃。此外，超疏水涂层具有优异的防污性能，有助于涂层长时间保持较高的近红外反射率。因此，制备的超疏水近红外反射涂料具有优异的防污性能，在建筑节能方面具有很大的应用潜力。
In this work, BiOClxBr1−xmicroflowers were synthesized as building blocks for superhydrophobic NIR reflective coatings. The molar ratio of Cl to Br had a great influence on the microstructure and optical properties of BiOClxBr1−x. As the increase of x value, the microflower structure tunes from loose to dense. The NIR solar reflectance of BiOClxBr1−xranges from 0.860 to 0.935. The BiOClxBr1−xcoatings reduced the inner temperature of the heat box by approximately 3.9 °C. Due to the three-dimensional hierarchical structure of BiOClxBr1−xmicroflowers, superhydrophobic cool coatings can be fabricated on various building materials, such as concretes, aluminum plates, and glasses. Moreover, the superhydrophobic coatings exhibit superior antifouling performance, contributing to retain high NIR reflectance of the coatings for a long time. Therefore, the prepared superhydrophobic NIR reflective coatings with superior antifouling property have great potential to be used for building energy-saving.
