Abstract
A thermally reversible and high performance polydimethylsiloxane (PDMS)-based network was easily achieved from a novel single molecular silicone-based Diels–Alder crosslinker, which was obtained via the combination of the thiol-acrylate Michael addition and Diels-Alder click chemistries in a straightforward one-pot fashion. The high flexibility of the silicone-derived crosslinker allows for good healing of complete cuts without the need of a pre-healing step to dissociate the dynamic DA bonds. The cut healing process was possible via a single heating step at 70 °C, reaching a relatively good healing efficiency, evaluated by a tensile strength recovery of above 80%.
