Abstract

The invention discloses a flexible electrochromic heat-insulating intelligent window film and a preparation process thereof. The window film adopts a vacuum physical vapor deposition process such as roll-to-roll magnetron sputtering or evaporation, and is sequentially plated on the surface of flexible substrates such as PET. Transparent conductive film layer, electrochromic functional film layer, solid thin film electrolyte layer, ion storage film layer, transparent conductive film layer to obtain flexible electrochromic functional window film; roll-to-roll magnetron sputtering continuous coating process, in PET Silver-containing multilayer thermal insulation window film is prepared on the surface of flexible substrates such as the Multifunctional smart window film. The flexible electrochromic heat-insulating intelligent window film of the present invention can further reduce the energy consumption of the window by more than 50% compared with the traditional low-radiation heat-insulating window film; compared with the existing electrochromic glass products, the cost is lower and the installation is more convenient And it is safer; compared with the existing flexible electrochromic film research and development technology, it has the advantages of better stability, better energy-saving and heat insulation characteristics, and the process is more suitable for mass production of large-size window films.

Description

technical field [0001] The invention belongs to the field of new material preparation, and relates to an energy-saving smart film applied on window glass in fields such as buildings and automobiles, in particular to a flexible electrochromic heat-insulating smart window film and a preparation process thereof. Background technique [0002] Building energy conservation is a key issue in the field of environmental protection today. Building energy consumption has accounted for more than 30% of the total energy consumption of human society, and the energy lost through door and window glass accounts for more than 50% of the total energy consumption of buildings. Therefore, the development of new energy-saving door and window glass materials has become the most effective solution to reduce building energy consumption. At present, the technologies widely used to reduce the energy consumption of door and window glass mainly include insulating glass, low-E low-E coated glass and low-...
