Color-changing polymer composition, ion-conductive composition, transparent electrode layer composition, and electrochromic device comprising same

An ion-conductive composition for an electrochromic device, comprising:

• an amount of about 20 to 40 wt % of a polymer matrix;
• an amount of about 20 to 40 wt % of a reactive POSS (polyhedral oligomeric silsesquioxane) material;
• an amount of about 20 to 40 wt % of a lithium salt, and
• an amount of about 20 wt % or less and greater than 0 wt % of a room-temperature ionic liquid based on the total weight of the composition, and a solvent component, wherein the solvent component comprises one or more selected from isopropyl alcohol (IPA), ethanol, methanol, acetone, toluene, methyl ethyl ketone (MEK), ethyl acetate, methyl isobutyl ketone (MIBK) dimethylformamide (DMF), and dimethyl sulfoxide (DMSO).
• all the wt % based on the total weight of the ion-conductive composition.
