Abstract

The invention discloses an electrochromism-thermochromism dual-response intelligent energy saving device and a preparation method thereof; the electrochromism-thermochromism dual-response intelligent energy saving device comprises a top conductive substrate, electrolyte, a composite film, and a bottom conductive substrate arranged in sequence from top to bottom; an energy saving window introduces the electrochromism features so as to further improve regulating ability on solar energy, and the window body color can be changed by controlling voltage; the device combines electrochromism visible light waveband with thermochromism near infrared waveband regulating features, has higher solar energy regulating ability and color regulating ability when compared with a VO2 thermochromism film, has better infrared regulating ability when compared with electrochromism unit, thus providing substantial application potential in the intelligent energy saving door and window field.

Description

technical field [0001] The invention relates to a dual-response intelligent energy-saving device and a preparation method thereof, in particular to an electrochromic-thermochromic dual-response intelligent energy-saving device and a preparation method thereof. Background technique [0002] Building energy consumption accounts for a very large proportion of the world's total energy consumption. According to statistics, my country's building energy consumption has reached 30% of the total social energy consumption. With the expansion of my country's urbanization scale, the advancement of urban construction, and the improvement of people's living standards, building energy consumption will increase year by year. At present, building energy conservation has become a major issue of common concern to all sectors of society, and it is an important guarantee for sustainable economic and social development. [0003] Windows are the least insulated building components. Smart window ...
