GAS BARRIER FILM FOR FLEXIBLE SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A gas barrier layer for a flexible substrate is provided to form a gas protection layer for a flexible substrate in short time by using a simple process. CONSTITUTION: A gas barrier layer for a flexible substrate comprises a step of surface treating a substrate to form an anion on a substrate surface(10); a step of impregnating the substrate with a cation polymer solution; a step of taking out the substrate from the cation polymer solution and drying the same; a step of impregnating the substrate with an anion polymer solution with nanoclay(40); and a step of taking out the substrate from the anion polymer solution and drying the same.
