Abstract
A flexible composite comprising a plastic foil, having an upper and a lower surface, and at least one dielectric barrier layer against gases and liquids which is applied directly to at least one of the surfaces by plasma-enhanced thermal vapor deposition and comprises an inorganic vapor-depositable material, is provided. The flexible composite can be used for constructing flexible circuits or displays and has a high barrier effect with regard to oxygen and/or water vapor.
