TRANSPARENT GAS BARRIER FILM AND THE FABRICATION METHOD

摘要

PURPOSE: A transparent gas barrier film with inorganic composition slope gradient is provided to simply and cheaply obtain inorganic composition slope gradient only by treating with UV ray. CONSTITUTION: A transparent gas barrier film comprises a substrate containing silicon, with an organic-inorganic hybrid section with inorganic composition slope gradient. The surface of the substrate contains 70% or more inorganic. A method for preparing the film comprises: a step of preparing the substrate containing silicon; and a step of treating the surface with UV ray and ozone to form the inorganic composition slope gradient.
