Abstract
A packaging material comprising a graphene-reinforced polymer matrix composite (G-PMC) is disclosed. The packaging material has improved barrier resistance to gas and liquid permeants. Also disclosed is a method of improving barrier resistance of a polymer to a permeant, the method comprising forming a graphene-reinforced polymer matrix composite within the polymer. The packaging material may be used for packaging food, drug, perfume, etc. and to make various containers.
