Abstract

The invention discloses a multifunctional controllable electrochromic device and a manufacturing method of the multifunctional controllable electrochromic device. The multifunctional controllable electrochromic device comprises a first substrate and a second substrate opposite to the first substrate. A first conductive material layer and a second conductive material layer are arranged on the inner side of the first substrate and the inner side of the second substrate respectively, an electroactive material layer is arranged on the inner side of the first conductive material layer, sealing adhesives are arranged on the periphery of the second conductive material layer and the periphery of the electroactive material layer, the sealing adhesives, the second conductive material layer and the electroactive material layer form a cavity in an encircling mode, and the cavity is filled with an electrochromic electrolyte solution. Compared with the prior art, the multifunctional controllable electrochromic device and the manufacturing method of the multifunctional controllable electrochromic device have the advantages that the semi-fixed and semi-free electrochromic device can solve the matching problem of a full-fixed electrochromic device and the layering problem caused by long-term voltage applying of a full-free electrochromic device and has good controllability, and the color and the optical properties of the whole device can be adjusted by adjusting the material of a free part.

Description

technical field [0001] The invention relates to the field of electrochemistry, in particular to a multifunctional controllable electrochromic device. Background technique [0002] The electrochromic device can change its own absorption or reflectance under a certain voltage, so as to adjust the light and temperature. Electrochromic technology has been developed for many years, and its application is also very extensive, involving many fields such as transportation, display, building energy saving, etc. With the continuous improvement and improvement of its technology, there will still be greater application prospects. [0003] According to the existence of electrochromic materials, electrochromic devices can be roughly divided into two categories: free type and fixed type. [0004] Free-type devices have been studied quite maturely. It is composed of cathodic electrochromic materials and matching anode electrochromic materials. These materials are all dissolved in the elect...
