▎ 摘　　要

NOVELTY - A water vapor-barrier transparent polymer complex film has a transparent polymer film layer, inorganic material film layer formed on the transparent polymer film layer, and a composite film layer formed of composite material including polyvinylidene fluoride and 0.001-0.5 wt.% reduced graphene oxide. The water vapor-barrier transparent polymer complex film has light permeability of less than 70%. USE - Water vapor-barrier transparent polymer complex film used as protection film of LCD element and organic light-emitting diode, plastic food receptacle for milk, beer and chemicals, agricultural chemical container, reservoir of chemical substance and fuel tank.
