Abstract
A composite material comprising a first layer of thermochromic perovskite; a second layer of antireflection material including an organic or inorganic polymer deposited on the first layer; and a third layer of hydrophobic material deposited on the second layer. A method for preparing the composite material is also addressed.
Claims25
A composite material comprising:
- a first layer of thermochromic perovskite including a surface;
- a second layer of antireflection material including a surface and comprising an organic or inorganic polymer, the second layer is deposited on the surface of the first layer;
- and
- a third layer of hydrophobic material deposited on the surface of the second layer;
- wherein the second layer and the third layer are configured to permit a suitable amount of water vapor to reach the first layer to allow for hydration and dehydration of the first layer for supporting thermochromism of the first layer, and wherein each of the first, second, and third layers remains light-permeable after the thermochromism.
