Embodiment Construction

[0048] As a specific embodiment of the present invention, Figure 1 to Figure 3 The structure, shape change and window structure of the thermally transitional liquid crystal-based film are exemplarily demonstrated.

[0049] Such as figure 1 As shown, the thermal transition liquid crystal-based film 10 of this embodiment includes a first structural layer 11 , an active layer 12 and a second structural layer 13 , and the active layer 12 is disposed between the first structural layer 11 and the second structural layer 13 . The active layer 12 includes a nematic liquid crystal medium 14 and a dichroic dye 15. Antioxidants and photostabilizers can also be added to improve oxidation resistance and photostability as required. Preferably, photocurable monomers and photoinitiators can also be added, Photocurable monomers and photoinitiators are dispersed in materials such as column-type liquid crystal medium 14 and dichroic dye 15, and are cured under the action of light such as ultra...

Abstract

The invention relates to a thermal conversion liquid crystal based thin film, a preparation method thereof and an intelligent window, the thin film comprises a first structural layer, an active layerand a second structural layer, and the active layer is arranged between the first structural layer and the second structural layer; the active layer comprises a nematic liquid crystal medium and a dichroic dye; the nematic-isotropic transition temperature of the nematic liquid crystal medium is between 30 DEG C and 40 DEG C. The film is convenient to use, low in cost and suitable for energy conservation of buildings.

Description

technical field [0001] The invention relates to the technical field of energy-saving buildings, in particular to a thermal transition liquid crystal base film, a preparation method thereof and an intelligent window. Background technique [0002] In the past few decades, the world's energy consumption has continued to grow steadily, which has had a profound impact on human society, economy and politics. About 20% of this consumption is used to heat or cool homes and commercial buildings. Therefore, it is necessary to eliminate losses and reduce the overall energy consumption of buildings. [0003] Although existing common windows have solar heat control coatings and insulation, they are static in nature. This means that the efficiency of static windows fluctuates during dynamic weather patterns, resulting in a net energy loss for the building. If it is possible to dynamically adjust the light (energy) transmission of the window according to the external weather conditions,...
