Nano yellow tungsten oxide may be applied to window heat insulation film, which has excellent photochromic properties and can shield most of the ultraviolet rays and near-infrared rays. And therefore, it improves human comfort. Building glass contains window glass, glass door, skylight, and so on. Yellow tungsten oxide not only has high heat insulation and high visible light transmittance, but may be used to construct microstructures on various substrates and may be modified to regulate surface wettability. In this way,…
