METHOD FOR MEASURING METAL ION PERMEABILITY OF POLYMER FILM AND APPARATUS FOR MEASURING METAL ION PERMEABILITY OF POLYMER FILM

摘要

The present invention provides a method for producing a polymer film, comprising the steps of: applying a voltage to the polymer film at a temperature of 5 to 250 in a state where one side of the polymer film is in contact with an electrolyte solution containing a metal ion, an organic solvent and an aqueous solvent; And measuring a rate of change in resistance or a rate of change in current of the polymer film over time after the voltage is applied, and measuring a metal ion permeability of the polymer film used in the measurement of the metal ion permeability of the polymer film / RTI
