Abstract

The invention provides a method for preparing a comb-type polyether polyurethane macromolecular ionic liquid material by hydroxy-terminated polyepichlorohydrin (PECH), mainly comprising four steps, wherein, the main chain and the short side chain of the obtained macromolecules both take polyether structures. A polyether chain is a flexible chain, with low glass transition temperature; the ether bonds on the main chain and the side chain can complex with some metal ions; and the side chain also comprises ionic liquid groups, thereby having higher conductivity and good mechanical property and wide range of applications. The prepared comb-type polyether polyurethane macromolecular ionic liquid material can realize adjustable conductivity and electrochemical windows of the material by compounding with small molecular ionic liquid or inorganic salt. The comb-type polyether polyurethane macromolecular ionic liquid material has the characteristics of flexible, transparent and easy molding.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, in particular to a method for preparing a comb-shaped polyether polyurethane macromolecular ionic liquid material from hydroxyl-terminated polyepichlorohydrin. Background technique

[0002] Ionic liquids, also known as room temperature molten salts, are liquid organic electrolytes composed entirely of anions and cations at room temperature. This type of electrolyte has good conductivity, wide electrochemical window, non-volatile and non-flammable in a wide temperature range, and is an electrolyte for batteries and electrochemical capacitors, with a good application prospect. However, liquid electrolytes are prone to problems such as electrode corrosion, electrolyte leakage, and short life. Therefore, it is very important to explore polymer solid electrolytes to replace liquid electrolytes.

[0003] Combining ionic liquids with polymers, bonding groups with ionic liquid structures to t...
