Abstract
In flexible barrier materials, the required barrier properties
are obtained via combinations of polymeric and inorganic
layers. In standard configurations like common laminates,
the barrier effect is achieved by the combined action of the
inorganic layer together with the substrate and an additional
polymeric top layer, whereas the inorganic layer alone
would be no barrier at all. For higher barrier requirements,
more complex systems are tailored, consisting of a sequence
of polymeric layers (organic or inorganic-organic hybrid
materials) and inorganic barrier layers. Their final functionality
is given by the bulk permeability properties of the
polymeric layers and their thickness and by the microscopic
and macroscopic properties of the inorganic layers.
In this paper, the defect structures of the inorganic layers -
as assessed via different analytical methods - are used as
basis for numerical simulations, for which always a defect
dominated permeation mechanism was taken. The complexity
of the layer structures is increased stepwise, from the
known configurations of one inorganic layer on top of a
substrate and one inorganic layer embedded between two
different polymers up to a description of one polymeric layer
of varying thickness between two inorganic layers and its
extension to repeated sequences of this structure. The results
demonstrate the importance of the inherent barrier properties
of the polymeric interlayers as a scaling factor for the performance
of multi layer stacks.
