POLYARYLETHER-BASED POLYMER WITH SIDE CHAIN IN POLYETHYLENE GLYCOL STRUCTURE, SOLID POLYMER ELECTROLYTE AND PREPARATION METHODS THEREFOR

摘要

A polyarylether-based polymer with side chain in polyethylene glycol structure, a solid polymer electrolyte and preparation methods therefor are disclosed. The main chain of the polymer has a polymer structure containing a polyarylether group, the side chain has a polyethylene glycol structure, and the structural formula of the polyarylether-based polymer is as follows:; ;and the preparation method for the polyarylether-based polymer with side chain in polyethylene glycol structure comprises: step (1): preparing a polymer containing a polyarylether group; and step (2): dissolving the polymer containing a polyarylether group and polyethylene glycol in a solvent, then adding a catalyst, dripping a coupling agent after the catalyst is dissolved, and conducting reaction while stirring to obtain the polyarylether-based polymer with side chain in polyethylene glycol structure. The all-solid polymer electrolyte prepared by the present invention has favorable ionic conductivity and excellent heat resistance, high temperature resistance and mechanical strength.
