Multilayer structure, electrochromic cell and ophthalmic device incorporating it, and methods for manufacturing the same

Abstract

Disclosed is a multilayer structure for an electrochromic cell, to a electrochromic cell and an ophthalmic device incorporating the multilayer structure, to corresponding uses of the multilayer structure, and to methods for manufacturing the multilayer structure, the electrochromic cell and the ophthalmic device. The multilayer structure includes:—a transparent flexible substrate including a thermoplastic polymeric film, the flexible substrate having two main surfaces, at least one being configurated to be a barrier to oxygen, water vapor and/or solvents, and—a electrically conductive layer which surmounts the flexible substrate to form a flexible first part of the electrochromic cell, the electrically conductive layer being configured to form an electrode of the electrochromic cell and including a deformable electrically conductive nanostructure. The flexible first part is formed to a curved shape defined by a first curvature including at least one of a cylindrical, toric and spherical curvature.
