Polymer electrolytes for electrochromic devices

Abstract The chapter begins by discussing the characters and composition of polymer electrolytes for electrochromic devices. It then describes the four types of the polymer electrolytes dry solid polymer electrolyte, gel polymer electrolyte, porous gel polymer electrolyte and composite solid polymer electrolyte, their preparation procedures and properties especially ion conductivity of the samples. Finally, new types of polymer electrolytes including proton-conducting, alkaline, single ionic polymer electrolytes and electrolytes with ionic liquids are also introduced.

Electrolytes which are ubiquitous in all electrochemical devices, are the key component for ECDs. As the public s awareness of environmental 

A material can be defined as electroactive or electrically responsive if it responds to an electrical stimulation with a reversible variation of one or more physicochemical properties. Owing to the ease of generation and processing of input signals of the electrical type, electrically responsive materials with tailorable functionalities are considered today as smart materials.
