Layer-structured graphene oxide (GO)/polyvinyl alcohol (PVA) nanocomposite coated polyethylene terephthalate films have been fabricated by spray coating. GO/PVA nanocomposite solution was prepared by decreasing the volume of GO solution via vacuum filtration and mixing with PVA. The obtained composite films show dramatic enhancement of hydrogen gas barrier properties.
