Abstract: A composite article comprises a substrate having at least a substrate surface and a graded-composition coating disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices or materials. An organic light-emitting device incorporates such a composite article to provide an extended life thereto.

Abstract: A composite article comprises two polymeric substrate layers, each of which has at least a diffusion-inhibiting barrier on one of the surfaces. The diffusion-inhibiting barriers are disposed such that they face each other within the composite articles. Electronic devices are disposed on such composite articles to reduce the rate of diffusion of chemical species in the environment into the devices.

Abstract: A method of forming a hydrogenated amorphous germanium carbon (?-GeCx:H) film on a surface of an infrared (IR) transmissive material such as a chalcogenide is provided. The method includes positioning an IR transmissive material in a reactor chamber of a parallel plate plasma reactor and thereafter depositing a hydrogenated amorphous germanium carbon (?-GeCx:H) film on a surface of the IR transmissive material. The depositing is performed at a substrate temperature of about 130° C. or less and in the presence of a plasma which is derived from a gas mixture including a source of germanium, an inert gas, and optionally hydrogen. Optical transmissive components, such as IR sensors and windows, that have improved abrasion-resistance are also provided.

Abstract: The present invention provides tough, high modulus, low density thermoset polyurethane compositions which are useful in general as, for example, cast structural materials and in a preferred embodiment can be cured directly onto an aircraft engine fan blade, thereby providing a lighter blade, without concomitant loss in structural integrity or blade performance due to, for example, resistance to foreign object impacts and fuel efficiency. In a preferred embodiment, the composition is comprised of bis-amine compounds reacted with isocyanate-functional polyether polymers in the presence of hollow polymeric microspheres. The thermoset polymer compositions are formed by casting into a mold which is formed by a cavity within the metallic or composite fan blade or guide vane in the form of a pocket and a removable caul sheet. After the elastomeric polyurethane foam is injected through at least one injector port into the mold, the foam is cured.
