Deformation Mechanisms and Morphological Evolution in Novel Adaptive Thermoplastic Polyurethanes with Shape- Memory Effect

The proposed experiment aims to study the deformation mechanisms of novel polyurethanes using a tensile stage, focusing onAbstract:
newly synthesized multiblock thermoplastic materials with crystallizable soft and hard segments. Time-resolved in-situ SAXS/WAXS
experiments will be conducted to explore the structural and morphological evolution of thermoplastic polyurethanes under strain, considering
their thermal history. Additionally, we will analyze phase composition and transitions during uniaxial deformation. Preliminary studies
indicate that phase separation of incompatible segments and their crystallization influence the supramolecular structure and shape memory
effect. The experiment will investigate these competitive processes and how temperature control during stretching impacts the materials'
morphology, chemical composition, and thermal prehistory.
