Zusammenfassung:An article comprising a polymeric substrate and at least one inorganic barrier layer, wherein the inorganic barrier layer has a stress not greater than about 400 MPa and a density of at least about 1.5 g/cm3. The article is preferably an optical device, such as an organic light emitting diode (OLED) or a photovoltaic (PV) module, wherein a silicon nitride barrier layer has been directly deposited on a flexible polymeric substrate via plasma enhanced chemical vapor deposition (PECVD).
