Description

Electrochromic lens and preparation method and application thereof
Technical Field
The invention relates to the technical field of electrochromic materials, in particular to an electrochromic lens, a preparation method and application thereof.
Background
Currently, the dimming glasses widely used mainly use photochromic materials to prepare photochromic lenses, which are lenses that change to dark color when exposed to light of a specific wavelength, typically ultraviolet light. When the light source is not irradiated any more, the original light transmittance is restored and the light becomes clear. Photochromic lenses can be made of glass or plastics, including polycarbonate, and the color change is achieved by silver chloride or other halides added to the lens, which are transparent to visible light when not irradiated by ultraviolet light, and which chemically react when irradiated by ultraviolet light, thereby absorbing some of the visible light and rendering the lens dark. The chemical reaction is a reversible reaction, so that the lens can restore to the original transparent state when the lens is no longer irradiated by ultraviolet light.
The photochromic material needs to be activated by ultraviolet light to generate chemical reaction, and the photochromic reaction process is relatively slow and cannot control the process, so that the defects of low color changing speed, poor color changing effect and incapability of intelligent adjustment exist. The electrochromic material is driven by external voltage or current, the optical performance of the material is changed in a stable and reversible way in the range of visible light, infrared light or ultraviolet light, and the electrochromic material has the characteristic of excellent color changing effect, so that the preparation of the dimming lens by adopting the electrochromic material is gradually paid attention to.
CN 113885265a discloses an all-solid-state electrochromic composite film system intelligent glass component and a preparation method thereof: (1) Two pieces of transparent conductive film glass are taken as substrates, the transparent conductive film glass is ITO or FTO coated glass, and a layer of WO with the thickness of 100-500nm is prepared on one piece of conductive glass by a magnetron sputtering method 3 Preparing a NiO-based film with the thickness of 100-500nm on another piece of conductive glass by using a magnetron sputtering method as an ion storage layer, wherein the base film is used as an electrochromic layer; (2) WO in the preparation by wet-chemical sol-gel processes 3 Preparation of Li with thickness of 100-500nm on base and NiO base film + Doped AlPO 4 The film is used as an ion transmission layer; (3) The two glasses were wet-chemically Li + Doped AlPO 4 The films are adhered together by a medium, and the wet chemical ion transmission layer in the middle of the glass component is cured by heat treatment. However, in the method, various methods are adopted to prepare each layer in the electrochromic film layer respectively and heat treatment lamination is carried out, so that the process is complex, and the light transmittance is easy to be adversely affected.
CN 111158167a discloses a dimmable color-changing glasses, which comprises: the glasses comprise a glasses frame, glasses legs and electrochromic lenses, wherein the glasses legs are pivotally connected to two ends of the glasses frame, and the electrochromic lenses are embedded on the glasses frame; the electrochromic lens includes: at least one set of electrochromic devices, a glass sheet or resin sheet on one side of the at least one set of electrochromic devices, a glass sheet or resin sheet on the other side of the at least one set of electrochromic devices. However, compared with all-solid-state inorganic electrochromic materials, the dimming glasses prepared by adopting the organic electrochromic materials have longer color-changing response time and shorter cycle service life.
In order to overcome the defects in the prior art, there is a need to provide an electrochromic lens with stepless dynamic adjustable light transmittance and rapid color change.
