Tungsten trioxide is a type of photochromic material that may be applied for producing window heat insulation film with high heat insulation and high transmittance of visible light, thereby reducing energy consumption (saving energy charge) and improving human comfort by shielding most of the near-infrared and ultraviolet rays. The heat insulation film may be applied in office, exhibition hall, clothing store, home, factory, and so on.
The study of photochromism has become one of the research hotspots in materials science. And the preparation of tungsten trioxide of different morphology has been deeply studied as the powder material plays a fundamental role in the research of experiments and practical applications. Therefore, it has important scientific significance to investigate the effective way to control the particle size and morphology of tungsten trioxide particles for promoting the industrial application of tungsten trioxide materials. And it also has guiding significance for the development of thermal insulation materials.
