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.

Abstract: Disclosed herein is a method for obtaining a material comprising mesogenic compounds forming a liquid crystal mix with a stabilized blue phase. The method includes the steps of a) inducing the liquid crystal mix, contained in a chemical composition, to form the blue phase, then b) illuminating the chemical composition with a light beam of visible wavelength in order to trigger the polymerization of monomers contained in the chemical composition, to obtain the material comprising the liquid crystal mix in the blue phase stabilized by the polymerized monomers. The chemical composition contains a mesogenic system and a chemical photo-initiator system adapted to trigger the polymerization of the monomers when illuminated by the light beam of visible wavelength, in which the mesogenic system includes the mesogenic compounds forming the liquid crystal mix, a chiral dopant adapted to induce the blue phase, and a monomer mix comprising the monomers adapted to polymerize.
