요약

The present invention relates to a technology for manufacturing a nanocomposite membrane comprising a graphene oxide coating layer with a thickness of 1 nm to 50 nm, which is formed on various supports and has nanopores, and a reduced graphene oxide nanocomposite membrane, and applying the membranes to gas separation. The graphene oxide nanocomposite membrane for gas separation of the present invention has excellent gas permeability and selectivity at the same time, and especially, excellent hydrogen gas permeability and hydrogen gas selectivity compared with carbon dioxide, and the reduced graphene oxide nanocomposite membrane has remarkably enhanced hydrogen gas permeability and hydrogen gas selectivity compared with carbon dioxide, and thus the membranes are applicable as a gas separation membrane in an industrial field involving a hydrogen separation process. Furthermore, a graphene oxide nanocomposite membrane for gas separation can be provided, in which strong binding force between a support and a graphene oxide coating layer is induced by modifying surfaces of various supports and thus the graphene oxide coating layer is not easily delaminated.
