APPARATUS FOR MEASURING OXYGEN-PERMEABILITY OF FILMS AND ELECTROCHEMICAL OXYGEN-PERMEABILITY MEASUREMENT USING SAME

摘要

PURPOSE: An apparatus for measuring oxygen permeability of film and method for measuring oxygen permeability using the apparatus is provided to easily measure an oxygen permeability by providing a uniform voltage to a sensor and converting a current into the oxygen permeability of a film. CONSTITUTION: A sensor includes a positive electrode and a negative electrode. The sensor is a general polarographic or galvanic sensor for inserting an electrolyte between the positive electrode and the negative electrode. The material of the positive electrode is a silver/cerargyrite(Ag/AgCl), a solder(Pb), a copper(Cu), and a cadmium(Cd). The material of the negative electrode is a silver(Ag), a gold(Au), a platinum(Pt), a spelter(Zn), and a carbon(C). The electrolyte is K2CO3 and Na2CO3, KCl, NaCl, NaOH, and KOH.
