Blue tungsten oxide electrochromic film may be used to produce an electrochromic glass, and therefore be applied building glass to obtain a smart window, which is also known as a smart heat insulating glass and a new energy-saving material. As you may have known, requirements for building energy conservation in China are getting higher and higher. Also, the requirements of the energy conservation and intelligence of doors and windows are also getting higher and higher. Nowadays, the types of energy-saving glass used for doors and windows are also increasingly abundant, and electrochromic glass has become a frontier and hot spot for research at home and abroad.

In recent years, China has issued a series of policies. For example, in 2013, the National Development and Reform Commission's “Guidelines for Key Products and Services for Strategic Emerging Industries” supported the promotion of smart glass products. In 2015, the State Council “Made in China 2025” focused on new materials including high-performance structural materials, dingal polymer materials, special inorganic non-metallic materials and advanced composite materials. This means that green building materials such as tungsten oxide smart glass will be popularized and applied.
