Description

technical field [0001] The invention relates to an inorganic photochromic and thermochromic multilayer thin film material, a preparation method and application thereof, and belongs to the technical field of intelligent energy-saving glass dimming. Background technique [0002] my country is a big energy consumption country in the world, not only consumes a lot of building energy, but also has a low energy utilization rate. It is estimated that building energy consumption generally accounts for one-third of the total energy consumption of the society. At the same time, the contribution rate of building energy consumption to the world's greenhouse gas emissions is as high as 25%. Emission reduction must prioritize building energy efficiency. Statistics show that 50% of building energy consumption is carried out through glass windows, which are the main channels for light and heat exchange between buildings and the outside world. Therefore, the development of a new type of sm...
