Abstract:
1. A method of making an edge-sealed barrier film composite, the method comprising: providing a substrate consisting essentially of a polymer; and placing a plurality of barrier stacks on the substrate such that an initial barrier stack is formed directly on the substrate, the initial barrier stack comprising at least one decoupling layer comprising an organic material and a barrier layer comprising an inorganic material such that the barrier layer of the initial barrier stack is deposited directly on the substrate, wherein the at least one decoupling layer of the initial barrier stack defines an area and is etched so that at least one edge thereof defines a gradual slope, and wherein the barrier layer of the initial barrier stack has an area that is greater than the area of the at least one decoupling layer of the initial barrier stack such that a decoupling layer of a subsequently-deposited barrier stack is sealed from the substrate by at least the barrier layer of the initial barrier stack, the placing comprising:
