Abstract

The present invention belongs to the field of functional high molecular material and electrochemical material technology, and is especially a kind of transparent non-water conducting proton material, which is based on side group type azacyclic polymer and used for solid electrochromic device (ECD). Side group type azacyclic polymer is made to compound with Lewis acid component and small molecular azacyclic compound is added to obtain the novel solid polymer as non-water conducting proton material with relatively high proton conductivity and high transparency. The solid ECD with the material as conducting ion layer has easy filming, easy dispersing and easy device packaging, compared with traditional small molecular lithium salt and inorganic proton electrolyte. The solid ECD has excellent chromic effect and high chromic response, and is suitable for making great area electrochromic device.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials and electrochemical materials, and specifically relates to a transparent non-aqueous proton-conducting material based on a side group type nitrogen heterocyclic polymer that can be used in an all-solid-state electrochromic device (ECD) and its preparation method. Background technique [0002] Polymer proton-conducting materials can be widely used in electrochemical devices such as proton exchange membrane fuel cells, electrochromic devices, supercapacitors, and sensors due to their high conductivity, wide operating temperature range, and fast ion transport speed. Most sub-conductive materials are hydrated membranes of sulfonated polymers. The development of all-solid-state electrochemical devices puts forward new requirements for polymer non-aqueous proton-conducting materials. In particular, all-solid-state electrochromic devices require high transparency in addition to non-...
