Abstract

The present invention relates to a method for forming a graphene protective film having gas and moisture barrier properties, to a graphene protective film formed by the method, and to the use thereof. A single-layer or multilayer graphene protective film can be used as a material for a barrier coating or bags, and improves the gas and moisture barrier properties of a variety of devices in a wide array of industrial fields to thereby maintain the electrical characteristics of devices over a long period of time.
