Violet tungsten oxide has photochromic properties so that it may be used to prepare a high performance photochromic thin film, that is, a heat insulating film, more specifically, a highly transparent thermal insulating film. According to the principle of photochromism, the thermal insulation film undergoes a color change reaction under the condition of light, and changes from colorless to blue, and has a good shielding effect on light intensity and ultraviolet light.

In addition, experts said that as the raw materials including tungsten oxide and the glass substrate are environmentally friendly and reliable, it will not cause damage to the ecological environment, overcoming the solid waste pollution caused by the traditional materials. Moreover, compared with other methods, the construction of such smart heat insulation film has the advantages of no pollution, easy operation, high efficiency, and no corrosion of the workpiece. And its greater advantage lies in its simple equipment and easy on-site operation.
