vo2 nanostructures, fabrication techniques and applications in smart coatings for green construction

exterior smart coatings have attracted a great interest in recent years for energy saving purpose and green construction. vanadium dioxide (vo2) is a good candidate for smart coating applications because of its promising thermochromic properties.

thermochromic characteristic of vo2 makes it capable of controlling near infrared reflectance in different temperatures. this performance is closely related to the phase composition and the microstructure, which are largely dependent on the synthesis method and growth control.

the high phase transition temperature (tc) of 68 °c becomes the limitation of its practical application. in this work, a hydrothermal fabrication method was developed to prepare w-doped thermochromic vo2 pigment for being applied in smart coatings.
