Influence of VO based structures and smart coatings on weather resistance for boosting the thermochromic properties of smart window applications.

Vanadium dioxide (VO)-based energy-saving smart films or coatings aroused great interest in scientific research and industry due to the reversible crystalline structural transition of VO from the monoclinic to tetragonal phase around room temperature, which can induce significant changes in transmittance and reflectance in the infrared (IR) range. However, there are still some obstacles for commercial application of VO-based films or coatings in our daily life, such as the high phase transition temperature (68 °C), low luminous transmittance, solar modulation ability, and poor environmental stability. Particularly, due to its active nature chemically, VO is prone to gradual oxidation, causing deterioration of optical properties during very long life span of windows.
