Complex polymer materials used in lightweight components for the hydrogen economy or for photovoltaics often have to withstand demanding physical stresses in addition to chemical stability. One example of this is gas barrier layers, which can be applied to thermally sensitive substrates using light-driven coating technologies. The aim of the project is to gain a better understanding of the structural properties of these materials that enable them to be used safely over long periods of time. To this end, gas barrier layers are applied to polymeric and metallic substrates by means of UV-assisted coating processes and subjected to application-relevant aging scenarios. The structural and chemical analysis of the material changes should generate insights into material-structure relationships that can also be used by companies in the Saxon economy. As a prerequisite for such investigations, experimental setups and methods for targeted material aging are established and used to investigate layer systems.
