Problems solved by technology

[0004] Although the above method can deposit WO on the conductive film 3 However, it is inconvenient to use when depositing on non-conductive materials such as glass lenses, and since lenses such as sunglasses and mobile phone curved screens are curved lenses, how to complete the curved surface coating of electrochromic lenses is an unsolved problem.

Abstract

The invention discloses a curved surface coating process for an electrochromic lens. The curved surface coating process comprises the following steps of step 1, carrying out hot bending on a substrate and cover plate glass; step 2, forming an electrochromic coating film on the substrate through magnetron sputtering; and step 3, bonding the cover plate glass and the substrate through an adhesive, wherein the step 2 comprises spraying a first transparent electrode layer, spraying an electrochromic layer, spraying an ion conduction layer, spraying an ion storage layer and spraying a second transparent electrode layer, and an eccentric cylindrical target is adopted for spraying during spraying. According to the process, the eccentric cylindrical target is adopted for curved surface spraying, the spraying film forming is uniform, the performance is relatively stable, the substrate and the cover plate glass are firstly subjected to hot bending to form a fitting angle, in the subsequent fitting process of the substrate and the cover plate glass, the electrochromic coating film is not subjected to the deformation acting force, and the stability of the electrochromic performance is ensured.

Description

technical field [0001] The invention relates to the technical field of electrochromic lenses, in particular to a curved surface coating process for electrochromic lenses. Background technique [0002] With the rapid development of science and technology, a large number of special materials have been developed; among them, the electrochromic element refers to the reversible color change property when a voltage is applied, and the coloring and decolorization of the electrochromic element can be achieved by driving the voltage The reaction changes the original transparent and colorless state into a colored state after electrification. Its structure is a multi-layer electrochemical device. Applying voltage to the element causes the substances in the element to undergo a reversible reaction of oxidation or reduction. The phenomenon of color change, the electrochromic element can be used in daily life, if the external sunlight is too strong or if you want to make the interior secr...
