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.
Claims12
A method for manufacturing an electrochromic device, the method comprising:
- providing at least two substrates 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 mixture, and a polymerization thermal activator;
- combining the dispersion phase and the dispersion medium to form an electrochromic composition comprising a colloidal dispersion in which the polymer is dispersed in the dispersion medium;
- filling the space with the electrochromic composition;
- and
- after combining the dispersion phase and the dispersion medium and after filling the space, polymerizing the polymerizable mixture in the colloidal dispersion in the presence of the polymer dispersed in the dispersion medium.
