Abstract
An electrochromic composition is provided. The electrochromic composition includes 0.5˜10 parts by weight of a first oxidizable polymer, 0.5˜10 parts by weight of a reducible organic compound, 0.5˜20 parts by weight of an electrolyte, and 60˜98.5 parts by weight of a solvent. The first oxidizable polymer is a polymer of 1 molar part of diamine and 0.1˜20 molar parts of dicarboxylic acid, diacyl chloride, or dianhydride, a mixture of the aforementioned polymers, or a copolymer of the aforementioned polymers. An electrochromic element including the aforementioned electrochromic composition is also provided.
