Abstract
Disclosed are a color-changing polymer composition, an ion-conductive composition, and a transparent electrode layer composition for a painting-type spray coating process, and an electrochromic device including the same. The color-changing polymer composition for an electrochromic device includes an amount of about 5 to 30 wt % of a color-changing material, an amount of about 0.01 to 1 wt % of ferrocene, an amount of about 10 to 30 wt % of a polymer matrix, an amount of about 0 to 70 wt % of an ion-conductive material, and an amount of about 1 to 10 wt % of a POSS (polyhedral oligomeric silsesquioxane) derivative, based on the total weight of the composition.
