A composite article comprises a substrate (340) having at least a substrate surface and a graded-composition coating (350) disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating (350) reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate (340) such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices (320) or materials. An organic light-emitting device (310) incorporates such a composite article to provide an extended life thereto.

La présente invention concerne un article composite qui comprend un substrat (340) comportant au moins une surface de substrat et un revêtement d'une composition variable (350) disposé sur une surface du substrat. La composition du matériau de revêtement varie de façon sensiblement continue sur toute l'épaisseur de ce dernier. Le revêtement de l'invention (350) réduit les vitesses de transmission de l'oxygène, de la vapeur d'eau et d'autres espèces chimiques à travers le substrat (340) de façon que l'article composite peut être utilisé de manière efficace comme une barrière de diffusion afin de protéger des dispositifs (320) ou des matériaux chimiquement sensibles. L'article composite de l'invention est intégré dans un dispositif électroluminescent organique (310) afin d'allonger sa durée de vie utile.
