Abstract

The invention provides a preparation method for epoxy propyl ionic liquid and its polyether type macromolecular iconic liquid, which is characterized in that: due to the epoxy propyl structure in the epoxy propyl ionic liquid, the dissolving ability, conductibility and polymerization is better; polymerization is carried out for the epoxy propyl ionic liquid, to acquire polyether type macromolecular iconic liquid; main chains of the polyether type macromolecular iconic liquid are flexible chains with low glass-transition temperature; complex occurs between ether bonds of the polyether type macromolecular iconic liquid and certain metal ions; high-density ionic liquid groups are arranged on side chains, thereby higher conductivity, better compatibility with small molecular iconic liquid as well as inorganic salts, and excellent mechanical property are capable of being realized for the polyether type macromolecular iconic liquid. Adopted as raw materials for electrochemical devices such as batteries, capacitors and color alteration apparatus for light, the preparation method for epoxy propyl ionic liquid and the polyether type macromolecular iconic liquid has the advantages of broad prospect and application areas.

Description

technical field [0001] The invention belongs to the technical field of chemistry and macromolecular materials, and in particular relates to a method for preparing polyether type macromolecular ionic liquid from glycidyl ionic liquid. Background technique [0002] In recent years, room temperature ionic liquids have attracted extensive attention from academia and industry as a "green solvent" and a new type of electrolyte. Room temperature ionic liquids refer to salts that are mainly composed of organic cations and inorganic and organic anions that are liquid at or near room temperature. At present, room temperature ionic liquids have been widely used in many fields such as catalytic reaction, organic synthesis, separation analysis, solid lubrication and electrochemical research. As a new class of "green solvents", room temperature ionic liquids have many characteristics that traditional solvents do not have: [0003] 1. Low melting point and wide liquid range; [0004] 2....
