Abstract
The invention relates to devices that provide a color change under the influence of an electric voltage, in particular to an electrochromic device and a method for manufacturing such a device. Disclosed is the method for manufacturing an electrochromic device comprising at least two electrodes that are flexible and optically transparent with a hermetically closed space between the electrodes filled with an electrochromic composition that may contain transparent and insoluble microparticles that function as spacers.
Claims13
A method for manufacturing an electrochromic device, the method comprising:
- providing at least two flexible electrodes having a space therebetween;
- preparing a dispersion phase comprising a polymer;
- preparing a dispersion medium comprising a liquid solvent, a cathodic component, an anodic component, a polymerizable monomer mixture, and a polymerization thermal activator;
- combining the dispersion phase and the dispersion medium to form an eletrochromic composition comprising a colloidal dispersion in which the polymer is dispersed in the dispersion medium;
- combining the electrochromic composition with transparent microparticles that are insoluble in the liquid solvent;
- filling the space with the electrochromic composition and hermetically sealing the space after filling;
- and
- after combining the dispersion phase and the dispersion medium and after filling the space, polymerizing the polymerizable monomer mixture in the colloidal dispersion in the presence of the polymer dispersed in the dispersion medium.
