Hetero-assembly design of 2D oxide nanosheets for tailored thermal shielding materials

“…The key to solving this issue is the development of high-performance thermal shielding films that can block NIR light from the sunlight while maintaining visible transparency. 2,3) Currently, the main targets of the thermal shielding films are NIR absorption materials based on transparent conducting oxides such as indium-tin oxide (ITO), [4][5][6] antimony-tin oxide, [7][8][9] and Cs 0.33 WO 3 . 10,11) However, these NIR absorption materials suffer from some drawbacks such as high shielding loss due to partial heat reradiation from the window and reduced visible transparency of thick films (with a typical thickness of 200−500 nm); these drawbacks often caused additional energy consumption.…”
