Abstract:
1. A method of forming a multilayer film for packaging applications by a solution process comprising the steps of: positioning a plurality of basic film structures in contiguous overlying relationship to form a multilayer film, each basic film structure of the plurality of basic film structures including one of a first two-layer structure with a first layer including a polymer/organic material and a second layer including a functionalized inorganic material, a second two-layer structure with a first layer including a polymer/organic material and a second layer including a polymer/organic binder, and a three layer structure with a first layer including a polymer/organic material, a second layer including a functionalized inorganic material, and a third layer including a polymer/organic binder; and the positioning, in conjunction with each layer of each of the plurality of basic film structures, including forming the materials of each layer into a solution; printing the solution to form each layer; and drying and annealing/curing the printed solution of each layer.
