Abstract

The invention discloses an electrochromic intelligent window and an anencapsulation method thereof. The electrochromic intelligent window comprises a first glass substrate, a first transparent conducting layer, an electrochromic layer, an electrolyte layer, a second transparent conducting layer and a second glass substrate laminated in sequence. The electrochromic intelligent window is characterized in that an encapsulation structure used for cladding and blocking an electrolyte solution of the electrolyte layer is further arranged between the electrochromic layer and the second transparent conducting layer. The electrochromic intelligent window and the encapsulation method thereof provided by the invention have the characteristics of good leakproofness and good encapsulation flatness, and the problems such as liquid leakage can be effectively prevented from occurring, and the electrochromic intelligent window is uniform in coloring.

Description

【Technical field】 [0001] The invention relates to an electrochromic smart window and a packaging method thereof. 【Background technique】 [0002] Electrochromism refers to the reversible change of color and transparency of materials under the action of an applied electric field or electric current, which is due to the optical properties (transmittance, reflectance or absorptivity) of materials in the ultraviolet, visible or near infrared region It is caused by a stable and reversible change under the action of an external electric field. In the early 1980s, American scientist C.M.Lampert and Swedish scientist C.G.Granqvist proposed a new type of smart energy-saving window based on electrochromic films, called Smart window, which is considered a milestone in electrochromic research. Liquid electrolyte is the most commonly used in electrochromic smart windows. In the vertically installed window structure, the electrolyte needs to be evenly distributed and not leaked, which has...
