Abstract:
This multilayer component (11) for encapsulating an element (12) which is sensitive to air and/or moisture comprises an organic polymer layer (1) and at least one barrier stack (2). The barrier stack (2) comprises at least one sequence of layers consisting of a retention layer (22) sandwiched between two high-activation-energy layers (21, 23), in which: - for each of the two high-activation-energy layers (21, 23), the difference in activation energy for water vapor permeation between, on the one hand, a reference substrate coated with the high-activation-energy layer and, on the other hand, this same reference substrate when bare is greater than or equal to 20 kJ/mol; and - the ratio of the effective water vapor diffusivity in the retention layer (22) on a reference substrate to the water vapor diffusivity in this same reference substrate when bare is strictly less than 0.1.

Abstract:
This substrate (11) for a device (50) that collects or emits radiation comprises a transparent polymer layer (1) and a barrier layer (2) on at least one face (1A) of the polymer layer. The barrier layer (2) consists of an antireflection multilayer of at least two thin transparent layers (21, 22, 23, 24) having both alternately lower and higher refractive indices and alternately lower and higher densities, wherein each thin layer (21, 22, 23, 24) of the constituent multilayer of the barrier layer (2) is an oxide, nitride or oxynitride layer.
