Abstract
An electrochromic polymer with polar side chains is disclosed. The viscosity of the electrochromic polymer is controllable by adjusting a ratio between polar side chains and alkyl side chains for forming the electrochromic polymer. The disclosed electrochromic polymer with polar side chains can be also made into a film with a controllable thickness by coating.
