Title: Development of new methods for the preparation of solid samples for the NMR analysis of synthetic polymers using dynamic nuclear polarisation.

Description: The knowledge of the structure-property relationships in polymer materials is fundamental to understand and predict their macroscopic applications and aging behavior. In this context, NMR appears as a viable option because it is a non-destructive technique that can study polymer materials in the solid-state with atomic resolution, and access their supramolecular structure over a large range of molecular weights without the need of translational order. However, this information is often hindered by the low sensitivity of NMR. Recently, we have shown how such inherent limitation could be strongly alleviated with the help of Dynamic Nuclear Polarization (DNP), which enhances solid-state NMR sensitivity by transferring the electron spin polarisation of exogenous paramagnetic sources to nuclei via microwave irradiation of the sample at cryogenic temperature. Notably, our work has shown the strong potential of DNP for the structural elucidation of functional polymers, but has also revealed that the sample preparation methods currently available for DNP are far from being optimal in the case of polymeric materials. The aim of this work is to develop new efficient methods for DNP sample preparation by exploiting technologies borrowed from process engineering for the analysis of functional polymeric materials by DNP NMR.
