First Claim
1. A method for manufacturing an electrochromic device comprising at least two flexible electrodes and a hermetically closed space between the at least two flexible electrodes, at least one of the at least two flexible electrodes being optically transparent, wherein the hermetically closed space between the at least two flexible electrodes is filled with an electrochromic composition, the method comprising:
- (1) preparing an initial deaerated eletrochromic composition in the form of an electrochromic dispersion system containing at least one of a suspension and a colloid, wherein a dispersion medium of the electrochromic dispersion system comprises an electrochromic solution comprising a liquid solvent, a cathodic component, an anodic component, a polymerizable low-shrinkage monomer or a monomer mixture, and a polymerization thermal activator, wherein the dispersion phase consists of a highly dispersible polymer, and wherein the initial electrochromic composition is deaerated to remove the dissolved oxygen of air that were introduced with the highly dispersible polymer;
(2) filling the hermetically closed space between the at least two flexible electrodes with the deaerated initial electrochromic composition, and (3) sealing the hermetically closed space between the at least two flexible electrodes.
