Resumen:
In this presentation, the study of furan-based thermoset polyurethanes, which were prepared in a one-pot fashion and self-mended under mild temperature conditions, will be given. Diels-Alder thermoreversible covalent bonds were introduced as crosslinkers into a shape-memory polyurethane material, improving thereby the material mechanical properties. When a crack occurs, Diels-Alder bonds will preferentially break, regenerating free furan/maleimide functional groups. The shape memory effect favors the crack closure upon heating, resulting in a reformation of the reversible crosslinking bonds.
