THERMOCHROMIC MATERIALS FOR REFLECTIVE COATING
Keywords:thermochromic materials, vanadium dioxide, reflective coating
Thermochromic materials respond to change in external temperature. There are many thermochromic materials attended in recent years for energy conservation. Vanadium dioxide (VO2) is a well-known thermochromic materials. The reversible mechanism can be useful for thermal reflective coating of buildings reduces the temperature. This work is to investigate the ability of molybdenum (Mo)-doped VO2 powder for mixing in paint to be used as thermal reflective coating for concrete surface. Three different powder coatings were used. The effect of different type of surface coating on temperature variation of the surface concrete has been evaluated. This work demonstrates a novel approach that Mo-doped VO2 can be potentially used to reduce the temperature on the concrete surface and further retains indoor passive thermal comfort.
