US 2025/0036000 A1 · ELECTROCHROMIC VARIABLE-TRANSMITTANCE GLASS AND PREPARATION METHOD

Abstract

This application describes an electrochromic variable-transmittance glass and its preparation method. An example electrochromic variable-transmittance glass includes an electrochromic variable-transmittance film device, glass, and laminating adhesive. Laminating adhesive is positioned on one side of each opposing surface of the two glass pieces. The electrochromic variable-transmittance film device is sandwiched between the two glass pieces and wrapped by the laminating adhesive. The electrochromic variable-transmittance film device comprises conductive tape electrodes, lead-out electrodes, and a protective layer. The conductive tape electrodes are situated on the conductive substrate of the electrochromic variable-transmittance film device. The lead-out electrodes are positioned on the conductive substrate or the conductive tape electrodes and are conductively connected with the conductive tape electrodes, extending to the outer side of the glass for connection to an external power source. The protective layer covers the conductive tape electrodes and seals them onto the conductive substrate.
