Compression molded, alternating (A-B-A)n multilayered, and single layered extruded polymer films containing phosphate glass (Pglass) for high gas barrier applications were produced and evaluated. These polymer composites incorporated a range of glass transition temperature (Tg) glasses, and were produced using several different extruder configurations. Oxygen permeability of this family of material was generally in agreement with Cussler model for dense dispersions of platelet-like fillers. The structure, morphology and the samples will be presented, furthering our understanding of gas transport in layered composite materials.
