The methodcan be used for preparing the flexible low-working voltage polyaniline electrochromic emissivity film.

Description

technical field [0001] The invention relates to a preparation method of an electrovariable emissivity thin film. Background technique [0002] Energy consumption and climate change are two major problems facing mankind in the 21st century. High energy consumption directly leads to excessive emissions of greenhouse gases, seriously disrupting the climate balance, leading to global warming and extreme weather. Therefore, the development of renewable energy is imminent. On the other hand, reducing current energy consumption and improving energy efficiency are equally important. In fact, improving energy efficiency through the use of energy-efficient appliances or building design is the most effective way to solve energy problems compared to using other energy sources. Space heating and cooling are the main components of current energy consumption, accounting for 12.3% of the total energy consumption. Reducing the intensity of indoor temperature regulation will have a signif...
