Abstract
A glass container is disclosed that includes a glass substrate and a cold-end coating applied over, and preferably in direct contact with, an exterior surface of the glass substrate. The cold-end coating includes encapsulated graphene in which graphene particles are surrounded by and distributed within a polymer matrix material. The graphene may include multilayer graphene and the polymer matrix material may include ethylene acrylic acid copolymer, polyethylene oxide, or both ethylene acrylic acid copolymer and polyethylene oxide. A method of applying a cold-end coating during manufacture of a glass container is also disclosed in which a coating composition is applied over an exterior surface of a glass substrate having a container shape. The coating composition is a heterogeneous solution that includes one or more emulsified organic polymers and suspended graphene.
