Composite system, useful e.g. for protecting oxygen-sensitive components in electronic or electrical devices, comprises a substrate foil and at least one scavenger-/indicator layer containing a metal as oxygen sorbent

摘要

Composite system comprises a substrate foil and at least one scavenger-/indicator layer, which is separated in the vacuum as a thin film, contains at least a metal as oxygen sorbent, where the sorption of oxygen changes at least a physical characteristic of the oxygen sorbent, and at least a stationary activator, which is in direct contact to the scavenger layer, for the oxidation of oxygen sorbent.
