RADIATION-INDUCED GRAFTING REACTION METHOD AND METHOD FOR PRODUCING SOLID POLYMER ELECTROLYTE FILM

摘要

PROBLEM TO BE SOLVED: To provide a radiation-induced grafting reaction method having improved grafting reaction efficiency to shorten the grafting reaction time and provide a method for producing a solid polymer electrolyte film.

SOLUTION: The radiation-induced grafting reaction method comprises a radiation step to apply radiation to a polymer material 1 and a grafting reaction step to apply ultrasonic wave to a reaction liquid containing a radical-polymerizable monomer and immerse the polymer material to form a graft polymer chain. The method for the production of the solid polymer electrolyte film uses the radiation-induced grafting reaction method.
