The ambition of IIA research topic is to develop new ageing methodologies and analyses at different scales, enabling us to identify the parameters influencing the degradation mechanisms of materials and interphases in order to develop prediction tools to determine the materials durability.
The complexity of phenomena at interfaces is partly solved by the development of controlled chemistry and organization systems on different scales (time, dimension) considered as models of interphases to establish robust structure-property relationships. The contribution of numerical modeling enables us to understand the phenomena involved, and to propose innovative solutions for more sustainable and environmentally-friendly products and structures.
The originality of our approach lies in the combination of multi-scale thermal and mechanical characterization methods (static and dynamic mechanical testing, nano-mechanical mapping and even numerical modeling). Our work also relies on spectral characterization tools (fluorescence spectrometry, FTIR and Raman spectrometry) to highlight polymer degradation.
Our team pays particular attention to structure-properties relationships and ageing of emerging materials and topics including sustainable, recyclable and adaptive materials, 3D-printed structures and microplastics marine degradation.
