Shape-memory polyurethanes for polar wearables with ultrasensitive multi-monitoring.

ABSTRACT: Integrating environmental stability and multi-monitoring modules into flexible sensor remains a pivotal scientific challenge. This study presents a supramolecular polyurethane (PU) engineered with fluorine-rich segments that form electrostatic crosslinks with positively charged ionic groups at polymer chain terminals and establish fluorine-dipole interactions with blended ionic liquid (IL) to stabilize ion transport pathways. The resulting ionically conductive elastomer combines shape memory capacity, self-healing property, and cryogenic tolerance, retaining robust mechanical strength (~32.31 MPa), toughness (~107.05 MJ m⁻³) and substantial ionic conductivity even at -40 °C. Notably, it exhibits a high temperature coefficient of resistance (TCR = 8.05% °C⁻¹) at cryoge
