Problems solved by technology

[0007] In short, the reflective layer provided by the present invention can solve or improve the time efficiency problem of radiative heating annealing of the vanadium oxide film layer, and the setting of the composite barrier layer can realize that the thermochromic smart film containing the vanadium oxide film layer can withstand relatively high pressure in vacuum and atmospheric environments. After a long time annealing treatment, the vanadium oxide film layer will not be oxidized or reduced to deteriorate, and a thermochromic smart film product with better weather resistance can be obtained

Abstract

The invention relates to a thermochromic intelligent film and a preparation method therefor. The thermochromic intelligent film consists of a substrate and a complex film layer, wherein the complex film layer comprises a thermochromic functional layer with ambient temperature adjusted heat, a film layer with an infrared reflection function is arranged at the lower part of the thermochromic functional layer and can be used for increasing the efficiency of annealing, a barrier layer which is used for preventing the thermochromic functional layer from oxidation or reduction metamorphism in a heat-treatment annealing and crystallizing modification process is arranged on the thermochromic functional layer, and a dielectric film layer is arranged on the barrier layer and is used for adjusting the appearance color and other protective actions of the complex film layer. The thermochromic intelligent film has the characteristics that the arrangement of the infrared reflection layer is beneficial to the increase of annealing efficiency, the arrangement of the barrier layer is beneficial to the improvement of crystallization quality of the thermochromic functional layer, and meanwhile, the heating annealing treatment on the complex film layer in an atmospheric environment and a vacuum environment can be achieved. According to the thermochromic intelligent film disclosed by the invention, after related film layers are subjected to vacuum plating, the crystallizing modification of the film can be carried out by adopting infrared vacuum-atmosphere environment, infrared atmospheric environment or tempering furnace heat treatment.

Description

Technical field: [0001] The invention relates to a thermochromic smart film and a preparation method thereof, in particular to the problem of promoting high-efficiency heating crystallization modification in the heat treatment process of the smart film and preventing the annealing crystallization oxidation or reduction deterioration of the thermochromic functional layer. Background technique: [0002] For the mass production of thermochromic smart films, there are two traditional preparation process routes, namely chemical spraying thermal decomposition and sputtering coating. The thermal decomposition of chemical spraying has certain limitations due to the control of its appearance color, film thickness, etc., and its industrial production is seldom used. Compared with chemical spray thermal decomposition, sputtering coating has more advantages, such as easy control of film composition, easy control of film thickness and good repeatability. Since the formation of the therm...
