Abstract

The invention provides a vanadium dioxide-based thermochromic composite film and a preparation method thereof, and belongs to the technical field of building energy conservation. The preparation method of the vanadium dioxide-based thermochromic composite film provided by the invention comprises the following steps: 1) preparing vanadium dioxide-based thermochromic film slurry; (2) preparing thermochromic polymer slurry; and 3) preparing the composite membrane. The preparation scheme adopted by the invention is simple, is easy for mass production, can be used in the aspects of thermochromic intelligent energy-saving films, intelligent energy-saving windows and the like for buildings and vehicles, and can realize rapid popularization of the vanadium dioxide-based thermochromic energy-saving window application technology. The composite film provided by the invention has an obvious indication effect, the problem that the color of the vanadium dioxide-based thermochromic composite film is not attractive can be improved, and the material stability and the display effect of the composite film are improved.

Description

technical field

[0001] The invention relates to the technical field of building energy conservation, in particular to a vanadium dioxide-based thermochromic composite film and a preparation method thereof. Background technique

[0002] With the rapid development of the economy and society, the demand for energy has risen sharply, and the global energy shortage has become increasingly serious. According to statistics, building energy consumption accounts for 30% to 40% of the total energy consumption in society. Promoting building energy conservation is one of the key measures to achieve sustainable development. one. Building services such as air conditioning, heating and ventilation are the main components of building energy consumption, accounting for 50% of the total building energy consumption. However, only 50% of the energy used in air conditioning and heating is effectively used, and the rest is lost through heat exchange with the outside world. As the main channel f...
