    Mechanical Properties of Confined Phase Changing Materials

    Résumé : Fundamentally new paradigms are expected to emerge for the fields of soft matter and mechanics at the nanometer scale. Those new behaviors stem principally from two distinct effects : (i) a breakdown of the continuum concepts of mechanics when reaching molecular sizes for which the granularity of matter has to be accounted for and (ii) the increasingly predominant role played by interfaces and surfaces in nanoscale systems, leading to the appearance of new force scales (Van der Waals, electrostatic forces...). Many macroscale phenomena in soft matter take their origin at the nanoscale, and can thus be illuminated by experiments at those scales. In this talk I will present our recent Scanning Probe Microscopy studies of the mechanical properties of soft matter phase changing material and we will see how the the physical and chemical properties of the confining material impact drastically the phase transition as well as the mechanical properties of the confined soft matter system.
