Vanadium dioxide based composite foils with solar modulation ability of 13.6% were prepared by an all-solution process for the first time, for application in smart windows.
VO2 is a key material for thermochromic smart windows that can respond to environmental temperature and modulate near infrared irradiation by changing from a transparent state at low temperature to a more reflective state at high temperature, while maintaining visible transmittance.
