Abstract
A barrier film. The barrier film may include a substrate, an inorganic layer disposed on a side of the substrate, and an organic layer-by-layer structure disposed on a side of the inorganic layer, where in the organic layer-by-layer structure comprises a layer of a cationic polyelectrolyte and a layer of an anionic polyelectrolyte.
Claims15
A barrier film comprising:
- a substrate;
- an inorganic layer disposed on a side of the substrate;
- and
- an organic layer-by-layer structure disposed on a side of the inorganic layer, wherein the organic layer-by-layer structure comprises a layer of a cationic polyelectrolyte and a layer of an anionic polyelectrolyte.
